This circular diagram represents the genetic code, showing how the four nucleotide bases of RNA (adenine [A], cytosine [C], guanine [G], and uracil [U]) form codons that specify amino acids. Each ...

The often-mentioned fact that humans and chimpanzees are 99.9 percent identical in their DNA is hard to accept for some people, who can't comprehend how we could share so much of our basic genetic ...

Despite awe-inspiring diversity, nearly every lifeform – from bacteria to blue whales – shares the same genetic code. How and when this code came about has been the subject of much scientific ...
