article imageOp-Ed: Does 'junk' DNA really exist?

By Eliot Elwar     Sep 7, 2012 in World
When James Watson and Francis Crick discovered the DNA structure in the 1950s, they triggered a science revolution. Their findings, contributed to the human genome sequencing completion in 2003. Today geneticists realize that there is no junk in DNA.
From the HHMI research news: DNA’s stretches are critical to life's machinery that they have been “ultra-conserved” for many generations. Researchers have found the same sequences in humans, rats, and mice genomes; sequences that are over 95 percent identical to these are also found within dog and chicken genomes. Although many ultra-conserved genetic regions do not appear to code for proteins, they could play a regulatory role. These sequences are extremely significant to mammalian biology and small alterations in them would compromise any animal's fitness.
From the Washington Post: A person’s genetic risk for common diseases such as diabetes, cancer, and other ailments appear to be hidden within the shadowy region of the human genome referred to as “junk DNA.” However, most of human DNA appears to be involved in maintaining a person’s life, which was a view radically against the theories of many evolutionary biologists’ for the past decades.
From Science Blog news: Approximately one percent of the human genome contains genetic regions that code for proteins, raising the question: what is the rest of the DNA doing? Scientists have recently discovered the answer: most of the genome is biochemically active, and it is involved in regulating the nearby genes expression, according to a study from a large international team of researchers.
From Human Genome Project Information news: While the Human Genome Project completion was celebrated in 2003, the human chromosomes sequencing is essentially unfinished because the exact number of genes encoded by the genome remains unknown within the scientific community. The 2004 findings from the International Human Genome Sequencing Consortium (IHGSC), led in the United States by the National Human Genome Research Institute (NHGRI) and the Department of Energy (DOE), reduce the estimated number of human protein-coding genes from 35,000 to only 20,000 to 25,000 genes, which is an astonishingly low number for the human species.
From Human Genome Project Information news: Consortium researchers have confirmed the existence of 19,599 protein-coding genes in the human genome and identified another 2,188 DNA segments that are predicted to be protein-coding genes. In 2003, estimates from gene-prediction programs suggested there might be 24,500 or fewer protein-coding genes. The Ensembl genome-annotation system estimates them at 23,299. Even with improved genome analysis, computation alone is simply not enough to generate an accurate gene number. Therefore, gene predictions will have to be verified by labor-intensive work in the laboratory before the scientific community can reach any real consensus.
Analysis
According to many Darwinists, elements within the DNA’s portions were assessed to be "junk," which are leftovers from an imaginary evolutionary history no longer required for human life because they are superfluous coding biochemical information systems. However, with recent scientific advancements in genetic research, geneticists discover new complexity levels in DNA, and they realize that they need to learn more. The weight of scientific evidence demonstrates that "junk" DNA is not junk, but it offers benefits for the human body.
Fewer than two percent of DNA codes for proteins productions, employed for building bones, skin, other organ tissues, and red blood cells. For decades, evolutionists believed that DNA elements were considered excess baggage form human evolutionary past. In the early 1990s, the Human Genome Project (HGP) worked to map the human genetic code’s billions of chemical nucleotide bases. With great celebration, the HGP gave the world the human genome results in 2003. When the HGP began, a few Darwinists only wanted to map the genome sections that coded for protein because mapping the "junk" DNA was considered a waste of time. Evolutionists believed that it served "no known biological role.” However, recent scientific discoveries demonstrate that there is no junk DNA. The junk DNA theory illustrates how the religious philosophy of Darwinism prevents the progress of science.
Furthermore, 20 years ago, many geneticists expected humans to have roughly 100,000 genes, which would be far more than the lower animals. Scientists were shocked when they discovered that humans had only 20,000 to 25,000 protein coding genes, which is roughly the same number as a mouse. Moreover, rice possesses 28,000 genes and the puffer-fish has 27,000 genes, both have more genetic information than the human beings. While Yersinia Pestis bug contain 4,052 genes on one chromosome, humans have just six times as many on 46 chromosomes. The sea urchin contains 23,000 genes. This data indicates that there has to be more to human DNA than just blueprints for protein production. Therefore, by researching junk DNA, geneticists will discover additional functions and roles for DNA within the human genome because what Darwinists call junk DNA is just an unexplained genetic phenomena, which will be understood by future scientific research.
