Question

How might a gene mutation be silent, with no observable affect on a cell or an organism?

Answer 1

Answer:

D

Explanation:

There is approximately 64 base combination of codons (3 bases sequences) that are possible from the four bases nucleotides that make up our DNA. Yet there are only approximately 20 types of amino acids in our bodies. This means that other than the 4 start and stop codons, there is a lot of redundancy in the coding of amino acids by codons. Therefore some mutations on codons will have no effect on the type of amino acid translated. These are the silent mutations.
