The possible codons for Leucine in DNA are as follows: AAT, AAC, GAA, GAG GAT, GAC. Based on this, we see that they are the same in the second position (always A), and different in the first and third positions. This is called redundancy, where multiple nucleotide combinations code for the same amino acid.

WebAs previously mentioned, the genetic code consists of 64 64 unique codons. But if there are only 20 20 amino acids, what are the other 44 44 codons doing? As we saw, a few are stop codons, but most are not. Instead, the genetic code turns out to be a degenerate code, meaning that some amino acids are specified by more than one codon. WebJul 19, 2005 · For example, using B on sequences 250 and 500 codons long would result in the first sequence being seemingly different twice as much from the expected distribution as the second one. Moreover, the overestimation at 250 codons may amount to as much as a quarter of the dynamic range of B.
