Cracking the Genetic Code
... Cracking the Genetic Code You learned about the genetic code in Biology. It’s the mapping from nucleotide triplets in DNA sequences (via messenger RNA) to individual amino acids in the protein encoded by a given gene. You may recall that there are 64 “codons” (distinct triplets of G, A, C, and T) bu ...
