Yervant1 Posted May 4, 2006 Report Share Posted May 4, 2006 X-Men may be closer than you think Last modified: May 2, 2006, 4:58 PM PDT By Candace Lombardi Staff Writer, CNET News.com Small damages to sequences in the human genome are causing evolutionary changes in our DNA, according to a group of Japanese geneticists. Their recent findings prove that a common form of DNA damage caused by oxidation (called 8-oxoG) is a primary cause of mutagenesis, damage to DNA during the genome replication process that causes mutations in the resulting DNA molecules. Succinctly, the human race is genetically mutating, and we now may know how and why--at least in part. Japanese geneticist Yusaku Nakabeppu of Kyushu University and his team released their findings Monday in Genome Research. "Our findings suggest that 8-oxoG is one of the main causes of frequent recombinations and SNPs (single nucleotide polymorphisms) in the human genome, which largely contribute to the genomic diversity in human beings," the researchers concluded in their Genome Research journal article. DNA is made up of four nucleobases: adenine, cytosine, guanine and thymine. Combinations of these four bases make up the human genome. Among the four bases, guanine is the nucleotide most susceptible to oxidation, and the most common oxidation product of guanine is known as 8-oxoG (8-oxoguanine). It is this prevalent substance that is thought to cause SNPs. SNPs are subtle changes in chemical pairings found in the DNA sequence. SNPs and frequent recombination of code result in genetic mutation. These changes in chemical pairings sometimes cluster in one area of the DNA sequence but, until recently, scientists were unsure of why. Nakabeppu and his team have found a causal link between 8-oxoG and clusters of sequence variations in the human genome. While the specific environmental factors causing the mutation were not part of the research, the study established that the change is not happening in a closed system. The scientists agree with previous studies that have seen exposure to ionizing radiation and other environmental causes as genetic threats, according to their article. Previously, SNPs were thought to be natural occurrences caused by internal byproduct releases from chemical reactions. The Japanese researchers used genetic material from two healthy men and two healthy women (all unrelated genetically) in the study. Scientific American originally disclosed Genome Research's release of the findings. If Armenian geneticists were able to create a genome sequence by which they could alter the Armenian character intellectually and physically, what would you change? Mine would be to put in them some Armenian Unity trait, what is yours? Good luck to you all. Quote Link to comment Share on other sites More sharing options...
Sip Posted May 4, 2006 Report Share Posted May 4, 2006 Before this thread turns into another "evolution = global warming = religion = science = just belief" kind of thread, here are a few things I would change: 1. Remove the rabiz gene. 2. Swap the nose size and male organ size genes ... or alternatively, cross with a black gene. 3. Swap the body hair and head hair genes. 4. Remove the mustache gene in females. 5. Reduce the sweat gene in males. 6. Alter the wrist gene so that the joint is more suited for "xhorovats flipping" on the fire. 7. Increase the number of livers gene to process alcohol more efficiently. Hmmmm ... I think that's a start. I'm sure I'll think of more later.

Increase the number of livers gene to process alcohol more efficiently. Forget my choice I go with these two. Quote Link to comment Share on other sites More sharing options...
vava Posted May 4, 2006 Report Share Posted May 4, 2006 3. Swap the body hair and head hair genes. While were at it, we could also swap the "superiority complex" and the "humility" genes. Quote Link to comment Share on other sites More sharing options...
