Shakespeare 150x150 Shakespeare Sonnets Encoded in DNAWhile electronics engineers continually amaze consumers with technology that boasts more functions and greater memory capacity, researchers recently discovered a secret in nature that may revolutionize data storage. Using this natural wonder in space barely visible, scientists successfully stored the amount of information commonly held by approximately one million CDs. The wonderment capable of handling this vast amount of data is none other than deoxyribonucleic acid, commonly known as DNA.

Researchers acknowledge that many secrets contained within DNA remain uncovered. These invisible components of life hold the information necessary for recreating every living thing on the planet. Scientists now believe that this common but miniscule genetic material may hold the key to storing the ever-growing amounts of data created in the current technological society.

The size of the DNA strand required for harboring the phenomenal quantity of information appeared only slightly visible when contained within a test tube. The data that scientists recorded onto the DNA included all of Shakespeare’s 154 sonnets, a photograph, a complete scientific paper and a brief sound clip of one of Martin Luther King Mr.‘s speeches.

Researchers accomplished the feat by transforming a traditional binary code using the first four letters found in the nucleic bases of DNA. Adenine, cytosine, guanine and thymine comprise DNA. With this knowledge, scientists took the A, C, G and T for their DNA code. The initial attempt entailed using the A and C for the binary 0 coded, and the G and T represented the 1 code. However, the men encountered complications when translating the data back into a binary code. Scientists then created a more sophisticated code that more closely resembled the variations often found in DNA.

The new code converts one byte of data into a five-letter word made from the four letters. Scientists then combined these words into strings containing 117 letters each. They then overlapped these sequences, making decoding more consistent. The new code proved 100 percent successful and accurate. The storing process merely requires placing the synthetically produced DNA in a cold, dark, dry environment for indefinite lengths of time. This method of storage may hold the possibility of protecting data for centuries.

Scientists uncovered the resilience of DNA after extracting the code from a mammoth encased in ice for over 60,000 years. The durability of this incredible natural technology makes DNA encoding virtually destruction proof. DNA may prove a viable means of protecting our entire culture and library for eons. Sequencing and translating methods may change over time, but the code that forms the basis of all life never varies.

The research team believes that the ramifications for data storage using DNA remain staggering. The men suspect that given the recent discovery, a mere 41 grams of DNA might ably protect one quadrillion bytes of information. Until scientists simplify the method, the process requires too many complexities for everyday use.

While some may fear that researchers may use this coding for turning humans or other living things into science fiction super spies, scientists reassuringly claim that that scenario remains unlikely. The coding process required for this technology prevents insertion into living DNA. Anyone interested in the uses for identifying human DNA should visit GTLDNA.com.

AncestralOrigins 206x300 Discover your Ancestral Origins with DNA Ancestry Testing Ancestral Origins DNA Testing is a way to discover more about your genetic heritage. Every person is born with their own unique DNA. This genetic information remains constant throughout an individual’s lifetime. Each human being’s DNA tells their individual story. It also charts the beginnings of humankind in Africa and the eventual migration of humanity to every part of the globe.

Criteria Used to Determine Your DNA Ancestry

The process of determining your genetic heritage is threefold. Ancestral Origins testing separates the genetic information into three basic areas; populations, indigenous regions and strength estimates.

Populations

Using a color coded rating system; your DNA is compared to all the populations in their system. The color green on the map shows the strongest connection to a specific group and location. The color yellow relates to a significant link to particular areas and populaces and red suggest little or no connection. There are also correlations made to dispersed populations. Dispersed relates to groups of people, who were indigenous to one region, but traveled to another country or continent. This pertains to more recent movements of populations around the world.

Indigenous Regions

This testing reveals an ancient ancestry dating back over 80 thousand years. During the history of humankind there have been notable ancient migrations. One of the first migrations occurred, when people traveled out of Africa and up into Europe, then Asia and eventually to Australia. The last two migrations were to North and South America and the final journey was to the Pacific Islands.

Strength Estimates

This primary evaluation is an estimate of all the populations that are your strongest genetic links. The next assessment shows the most significant connections to indigenous regions. These calculations give a clear overview of all the data, so it is easier to determine your closest genetic matches.

Discovering Your Ancestral Origins

Ancestral DNA testing helps you to appreciate your genetic connection to particular groups and geographic origins. The DNA Ancestry tests can verify genetic relatedness to 14 identified anthropological areas and populaces. GTLDNA.com contains beautifully designed maps and graphs which makes the history and science of ancestral origins easier to appreciate.

Quadruple Helix DNA Found In Human Cells, May Aid Cancer Fight

Filed Under: In The News by dnatesting101 — Leave a comment

Scientists from the University of Cambridge have discovered quadruple helix DNA in human cancer cells. The result of a decade of research, the study published in Nature Chemistry may spawn new leads in the fight against cancer.

Normal DNA consists of the well-known double helix. The helices are made up of molecules called nucleotides. In a double helix, the nucleotides make up two ladder-like rails connected by rungs of more nucleotides. A quadruple helix has four rails in a square configuration with fractured rungs. They are also known to contain higher than usual amounts of the nucleotide guanine. Quadruplex structures have long been observed in laboratory settings. For the last twenty years, they have been known to grow in test tube experiments. However, the Cambridge study marks the first time they have ever been observed in living, human tissue.

DNA Quadruple Helix 300x229 Quadruple Helix DNA Found In Human Cells, May Aid Cancer Fight

In order to isolate these strange structures, the Cambridge scientists used an antibody attracted to the nucleotide guanine. By attaching a fluorescent bio marker to the antibody, scientists were able to isolate cancer cells with abnormal quantities of guanine. They then used a special compound to effectively “freeze” the quadruplexes in place for study. They discovered that quadruplexes only seem to appear when a cancer cell is about to divide. This may be a key insight into the dysfunction that causes cancer form and grow in healthy tissue.

The study theorizes that a similar method of antibodies and bio markers could be used to target cancer during cell division. By attacking the quadruplexes, it might be possible to halt the spread of cancer. Years of theorizing and working off of hypothetical models went into the Cambridge study. Synthetic experiments done on lab-grown quadruplexes preceded the experiment on human tissue. Dr. Julie Sharp with Cancer Research UK says the next step will be developing a similar methodology to find quadruplexes in tumors.

Cancer research has come a long way in the last twenty years. New techniques are being designed to target only cancer-affected areas, and testing for genetic predisposition has given people the tools to take precautions. This new research is another enormous step in the quest for a cure. Research supervisor Shankar Balasubramanian expressed hope that pharmaceutical companies would take the quadruplex discovery and run with it. However, he stressed that the function of quadruplexes is not yet understood. It is possible they evolved for a function.

“It’s a philosophical question as to whether they are there by design or not,” Balasubramanian said, “but they exist and nature has to deal with them. Maybe by targeting them we are contributing to the disruption they cause.”

Many are still skeptical if targeting quadruplexes is a viable form of treatment or not, the research has provided extraordinary insight into the growth of cancer. While the world awaits a true cure, advancements in precautionary steps and treatments continue. Every step makes the future a little brighter.

A Teenage Romance Revived After 23 Years, Thanks To A Paternity DNA Test!

Filed Under: DNA Testing, In The News by dnatesting101 — 6 Comments
December 30, 2010

DNA testing has become highly sought after in the last few years, whether it may to determine the Father of your born or unborn child, to find a missing relative, to find your biological mother, or even to solve a murder investigation. A paternity DNA test changed the world for Sarah Daniels and her son who were clueless as to who the dad was for over 23 years. The rekindling of their teenage relationship due a successful paternity DNA test was unpredicted.dna reunites couple m A Teenage Romance Revived After 23 Years, Thanks To A Paternity DNA Test!

Sarah Daniels at the age of 42 realized that the man she had originally thought was her son’s father, that fled once the child was born; 23 years ago. It wasn’t until recently when she ran into him again and realized that there was no resemblance. Sarah was confused and wasn’t sure who her son’s father was or how she would find out.

After a while she remembered Roy Cook with whom she had a short romance about 23 years ago before she even realized that she was pregnant. She acquired a DNA Paternity test kit and showed up at Roy’s door in January 2010. Roy was ecstatic to see her and took the test with any trouble. Once the results of the DNA test were analyzed, they confirmed that he indeed was the father.

Sarah’s first impression of seeing Roy open the door, reminded her of how much her son and Roy had looked alike. When she found out the good news she was overwhelmed but yet realized that she could finally relax because she had proof that Roy was the father and Danny, her son, would have someone to call “Dad.” Within a few weeks, Danny and Roy met and they shared a passion that made them seem as if they knew each other for years. Danny even called Roy “Dad”. Roy still had feelings for Sarah, so he proposed to her and as of December 29, 2010, they are engaged, with a long awaited marriage in their future. A DNA test can do more than just give you answers; it can change your life as it did for this family.

The Origins of DNA

Filed Under: DNA Testing by dnatesting101 — 2 Comments
December 12, 2010

DNA is such a fascinating and complex topic.  As important as DNA is, I find it interesting that its know-abouts have only been around since the late 19th century; however, since that time there certainly has been an increasing amount of discoveries since Johann Friedrich Miescher identified the unknown substance of what would later be known as, deoxyribonucleic acid (DNA).

Since DNA’s discovery science has been able to manipulate DNA in order to help people figure out their filial relationships, identify a deceased unknown person, track predisposed conditions for health prevention and probably the most popular, to determine a parent child relationships through DNA paternity testing.

DNA 246x300 The Origins of DNA

Do you have questions about DNA testing?

Imagine a time when DNA was completely unknown to our world and now it’s contributing to such above named advanced testing.

Here is timeline of DNA Milestones:

  • 1869 Johann Friedrich Miescher identifies an acidic substance in the nucleiu of human white blood cells. What was this? DNA (deoxyribonucleic acid).
  • 1912 The beginning stages of DNA’s structure are identified by a father and son physicists.
  • 1928 British medical officer, Franklin Griffith discovers the role that heat plays in DNA transformation.  This lead to the discovery that genetic material is a heat-stable chemical.
  • 1944 The transformation discovery by Griffith is identified by his colleagues as DNA.  Their discovery, however lead to many skeptics of this “too simple” of a molecule.
  • 1949 Biochemist, Erwin Chargaff’s research proves that DNA is specific to species.
  • 1953 James Watson and Francis Crick discover DNA structure.
  • 1962 Crick, Watson and Wilkins receive the Nobel Prize for determining the structure of DNA, only after nearly one hundred years and much skepticism.

He Wants A Paternity Test Even Before I am Pregnant?

Filed Under: DNA Testing, In The News by dnatesting101 — 16 Comments
November 15, 2010

 How would you feel about that? I recently came across an article where a Husband had requested that his wife take a paternity DNA test, even before she was ever pregnant. The husband continued to insist upon taking this even with their own parents present. husband wants paternity test 250b He Wants A Paternity Test Even Before I am Pregnant?According to him, he felt it was the “sensible”: thing to do. I am not sure things like this would be handled but it’s rather interesting to see what the modern world is developing into.

Paternity DNA testing has come a long way and can be highly useful in determining the father. This testing has also become very affordable making it more highly sought after by those looking for answers or scientific approval that they are the father. In the end, when the wife was pregnant, he continued to be persistent about it until the child was born and he saw the resemblance. In many cases, a paternity test is recommended in helping women figure out who the father of their child is.

What does this say about people in general? Are they afraid of infidelity? There’s a test for that too! It just shows that there is a lack of trust in relationships now due to the increased infidelity rates. If that’s the case, then just make the time to take an infidelity test and find out the truth. Whatever your needs maybe, DNA testing has come a long way in helping individuals scientifically find out important information. Just make sure you use an accredited DNA Testing Lab to ensure the finest results.
