    Scientists vie to break junk DNA's secret code By Roger Highfield, Science Editor (Filed: 06/10/2003) Huge tracts of human DNA, previously written off as meaningless junk, have been found to contain a hitherto unrecognised "genetic grammar", making the language of our genes much more complex than previously thought. The discovery is of potentially huge significance, since it could lead to an entirely new explanation for certain diseases and symptoms. A race is now on among teams of scientists worldwide to investigate this cryptic code. While the genetic recipe of a human being is spelt out with three billion letters of...

    Scientists are reporting a significant milestone for cancer research after charting 21 major mutations behind the vast majority of tumours. The disruptive changes to the genetic code, reported in Nature, accounted for 97% of the 30 most common cancers. Finding out what causes the mutations could lead to new treatments. Some causes, such as smoking are known, but more than half are still a mystery. Cancer Research UK said it was a fascinating and important study. A tumour starts when one of the building blocks of bodies, a cell, goes wrong. Over the course of a lifetime cells pick up...

    W.I.T. scientists, in conjunction with the Human Genome Project and Bob Jones University, have made what may be the most astounding discovery of this, or any generation. While working to understand and map the function of sequences of DNA in the human genome known as “Junk DNA” (for their lack of known function), scientists at W.I.T. noted that while the DNA sequences they were seeing bore little resemblance to the coding for biological function, they bore a striking similarity to the patterns of human language. Gene Bmp3 has a Retrotransposon sequence which translates to the well-known 1 Cor 6:19 “Do...

    ... So-called junk DNA, the vast majority of the genome that doesn't code for proteins, really isn't needed for a healthy organism, according to new research. "At least for a plant, junk DNA really is just junk — it's not required," said study co-author Victor Albert, a molecular evolutionary biologist at the University of Buffalo in New York. ...

    What makes us human? Some say that it is the development of language, though others argue that animals have language as well. Some say that it is our ability to use tools, though many animals are able to use rocks and other objects as primitive tools. Some say that it is our ability to see death coming. Now, researchers believe that they have found the definitive difference between humans and other primates, and they think that the difference all comes down to a single gene. Researchers from the University of Edinburgh in Scotland attribute the split of humanity from apes...

    The deepest look into the human genome so far shows it to be a richer, messier and more intriguing place than was believed just a decade ago, scientists said Wednesday. While the findings underscore the challenges of tackling complex diseases, they also offer scientists new terrain to unearth better treatments. … Encode succeeded the Human Genome Project, which identified the 20,000 genes that underpin the blueprint of human biology. But scientists discovered that those 20,000 genes constituted less than 2% of the human genome. The task of Encode was to explore the remaining 98%—the so-called junk DNA—that lies between those...

    Once considered unimportant "junk DNA," scientists have learned that non-coding RNA (ncRNA) -- RNA molecules that do not translate into proteins -- play a crucial role in cellular function. Mutations in ncRNA are associated with a number of conditions, such as cancer, autism, and Alzheimer's disease. Now, through the use of "deep sequencing," a technology used to sequence the genetic materials of the human genome, Dr. Noam Shomron of Tel Aviv University's Sackler Faculty of Medicine has discovered that when infected with a virus, ncRNA gives off biological signals that indicate the presence of an infectious agent, known as a...

    Deleting a non-coding region leads to narrowing of arteries in mice. Researchers have made headway in working out why a section of junk DNA — the 98% or so of the genome that does not code for proteins — raises the risk of at least one form of heart disease. About one in five deaths in the United States results from excessive build-up of fatty plaques inside arteries supplying blood to the heart — known as coronary artery disease (CAD). In 2007, genome-wide association studies1,2 on thousands of participants linked a non-coding stretch of chromosome 9p21 with the disease, and...

    A new concept making its way through the scientific community holds that just a few key changes in the right genes will result in a whole new life form as different from its progenitor as a bird is from a lizard![1] This idea is being applied to a number of key problems in the evolutionary model, one of which is the lack of transitional forms in both the fossil record and the living (extant) record. The new concept supposedly adds support to the "punctuated equilibrium" model proposed by the late Harvard paleontologist Stephen J. Gould. Dr. Gould derived his ideas...

    In the Darwinist repertoire, a standard response to evidence of design in the genome is to point to the existence of “junk DNA.” What is it doing there, if purposeful design really is detectable in the history of life’s development? Of course this assumes that the “junk” really is junk. That assumption has been cast increasingly into doubt. New research just out in the journal Nature Genetics finds evidence that genetic elements previously thought of as rubbish are anything but...

    The traditional understanding of DNA has recently been transformed beyond recognition. DNA does not, as we thought, carry a linear, one-dimensional, one-way, sequential code—like the lines of letters and words on this page. And the 97% in humans that does not carry protein-coding genes is not, as many people thought, fossilized ‘junk’ left over from our evolutionary ancestors. DNA information is overlapping-multi-layered and multi-dimensional; it reads both backwards and forwards; and the ‘junk’ is far more functional than the protein code, so there is no fossilized history of evolution. No human engineer has ever even imagined, let alone designed an...

    WASHINGTON (Reuters) - Primitive fish already may have possessed the genetic wiring needed to grow hands and feet well before the appearance of the first animals with limbs roughly 365 million years ago, scientists said on Wednesday. University of Chicago researchers were seeking clues behind a momentous milestone in the evolution of life on Earth -- when four-legged amphibians that descended from fish first colonized dry land. These first amphibians paved the way for reptiles, birds and mammals, including people. "What we're interested in here is the transition from fin to limb -- a great evolutionary event," palaeontologist Neil Shubin,...

    INTRODUCTION: For the past few years there has been a relatively public battle between Evolution (Darwinism) and Intelligent Design (ID). In courtrooms, classrooms and even at the polls, ID has been mostly losing this battle. Meanwhile, with the completion of the human genome project and the sequencing of many other species, scientific discoveries are upending many long-held assumptions of the pro-evolution community, but they don’t seem to realize it yet. The purpose of this article is to illuminate some of these discoveries and give hope to the ID community that steady, patient defense of our position will eventually win the...

As reported today in the Proceedings of the National Academy of Sciences (PNAS), regions of the human genome that were assumed to largely contain evolutionary leftovers (called “junk DNA”) may actually hold significant clues that can add to scientists’ understanding of cellular processes. IBM researchers have discovered that these regions contain numerous, short DNA “motifs,” or repeating sequence fragments,...

The term junk DNA refers to those portions of the genome which appear to have no specific purpose. But a team from IBM has identified patterns, or "motifs", that were found both in the junk areas of the genome and those which coded for proteins. The presence of the motifs in junk DNA suggests these portions of the genome may have an important functional role. These regions may...

    Scientists at the University of Illinois have discovered an antifreeze-protein gene in cod that has evolved from non-coding or 'junk' DNA. Since the creation of these antifreeze proteins is directly driven by polar glaciation, by studying their evolutionary history the scientists hope to pinpoint the time of onset of freezing conditions in the polar and subpolar seas. Professor Cheng will present her latest results at the Annual Main Meeting of the Society for Experimental Biology in Canterbury on Tuesday the 4th April [session A2]. Fish such as cod that live in subzero polar waters have evolved to avoid freezing to...

    Genetic material derisively called “junk” DNA because it does not contain the instructions for protein-coding genes and appears to have little or no function is actually critically important to an organism’s evolutionary survival, according to a study conducted by a biologist at UCSD. In the October 20 issue of Nature, Peter Andolfatto, an assistant professor of biology at UCSD, shows that these non-coding regions play an important role in maintaining an organism’s genetic integrity. In his study of the genes from the fruit fly Drosophila melanogaster, he discovered that these regions are strongly affected by natural selection, the evolutionary process...

    ANN ARBOR, MI - Results of a new University of Michigan study suggest that junk DNA - dismissed by many scientists as mere strings of meaningless genetic code - could have a darker side. In a paper published in the Aug. 9 issue of Cell, scientists from the U-M Medical School report that, in cultured human cancer cells, segments of junk DNA called LINE-1 elements can delete DNA when they jump to a new location - possibly knocking out genes or creating devastating mutations in the process.
