The words along the outside of the circle are the names of the amino acids that are coded for by the genetic code.
- The letters in the diagram represent the four bases of DNA: adenine (A), cytosine (C), guanine (G), and thymine (T).
- The diagram is read from the inside out, starting at the START codon and ending at the STOP codon.
- The amino acid that AAA is a codon to is that: AAA is a codon for lysine.
- The amino acid that GGA is a codon to is: GGA is a codon for glycine.
- The codons for alanine are GCU, GCC, GCG, and GCA.
- Three other codons for alanine are:GCU, GCC, and GCG.
The genetic code is a set of rules that describes how the four bases of DNA (adenine, guanine, cytosine, and thymine) are translated into the 20 amino acids that make up proteins. The code is universal, meaning that it is the same in all living cells.
So, a codon is a three-base sequence of DNA or RNA that codes for one amino acid. There are 64 possible codons, but only 20 of them code for amino acids.
