How do I use the genetic code to determine the exact codon for an amino acid?...
How do I use the genetic code to determine the exact codon for an amino acid? (ex. how do I find the exact codon for Lys?)
Homework Answers
Answer: Genetic code is a table representing three-letter nitrogenous bases that are nearly specific to a particular amino acid. This code is universal, that is is common for all organisms from prokaryotes to eukaryotes. The basic unit of genetic code is a codon. For 20 different amino acids, there are 64 such codons made of four nitrogenous bases, viz. Adenine (A), Guanine (G), Cytosine (C), and Uracil (U). The exact codon of Lys known from the table of standard genetic code is 'AAA' and 'AAG'. Similarly, other amino acids have their own specific codon. The standard table fo genetic code has been generated from lab experiments and needs to be remembered.

The genetic code is considered degenerate because most amino acids are encoded by at least two different codons. Some researchers have hypothesized that during evolution the genetic code has been optimized for its intended use in different organisms. Reseachers can study this by examining the relationship between the frequency with which an amino acid appears in all the proteins in an organism and the total number of codons for an amino acid. An optimized organism would use amino acids in...
