Moontanman Posted April 13, 2010 Report Posted April 13, 2010 Coding For Arthropods: What's So Special About Insects And Spiders? ScienceDaily (Apr. 30, 2006) — The central dogma of molecular biology is that DNA makes RNA makes protein. This relies on a specific underlying code which relates given triplets of RNA nucleotides into specific amino acids. Each of the 20 amino acids is represented by one or more RNA triplets, or codons: UAC is decoded as tyrosine, for example, and UGC as cysteine. (U is the RNA nucleotide containing uracil, A is adenine, C is cytosine, and G is guanine.) For some time the code had been thought to be the same in all organisms. But exceptions have been seen before, particularly in mitochondria. Coding For Arthropods: What's So Special About Insects And Spiders? Quote
