Question

A coding system based on "bits" of information read in groups of 3 is more than sifficient to code for all 20 amino acids. In fact, it is excessive. The number of different 3-base combinations involving 4 nucleotides is 4^3 or 64. With this many combinations, some amino acids are coded for by more than one 3-base sequence. For example, the m
RNA sequences GCU,GCC,GCA, and GCG all code for the amnino acid, alanine. How would redundancy in the genetic code influence whether a mutation in DNA would have an effect or not?

Explanation / Answer

http://www.nobelprize.org/educational/medicine/dna/a/translation/trna_wobble.html Generally the 3rd nucleotide has no effect on what kind of amino acid will be transcribed. Therefore, often times in every 3rd nucleotide, it will have no effect. :) Good luck!!!
