These are comprised of 20 unique amino acids, and each is coded for by a stretch of DNA known as a codon. Codons are always 3 base-pairs (nucleotides) in length. DNA is made of 4 unique nucleotides; (A)denine, (G)uanine, (C)ytosine and (T)hymine. This means that there are 64 unique codons that can be made with these 4 bases (4*4*4). If codons were only 2 bases in length then the variety of codons that could be created would be less (only 16 unique sequences if there are still 4 nucleotides). More unique nucleotides would be required to get enough unique sequences to code for the 20 amino acids (as well as the STOP codons).
The anticodons of tRNA adapt each three-base mRNA codon to the corresponding amino acid, following the genetic code : 2. Explanation of the Codons Animation. 1  Most images show 17 base pairs. 2  For the Codons animation, the left-most two base pairs are hidden, leaving exactly five 3-base codons (15 base pairs).he anticodons of tRNA adapt each three-base mRNA codon to the corresponding amino acid, following the genetic code : 2.
