Why do some amino acids have so many codons?

Hi Laura,

Genetic code is degenerate code, meaning that some codons may have similar functions or produce the same output. Hence some amino acids will have more than one codon.

Good example: Leucine has codons CUU, CUC, CUA, CUG. You can almost say that Leucine is CUx, where x is any ribonucleotide base.

All have the same function and produce the same output.

Hope that helps.
