A. it is due to mutations.

B. There are only 20 amino acids and 64 possible combinations

Answer:

B

Explanation:

i think it is b, because if they have 20 amino acid, 64 possible combination

they will be able to combine between themselve

Answer:

B. There are only 20 amino acids and 64 possible combinations

Explanation:

  • The genetic code is degenerate this means that more than one codon codes for a single type of amino acid.
  • This degeneracy occurs because there are 64 possible triplets of the bases that exist however there are only 20 amino acids known to encoded by the genetic code.
  • Out of this 64 possible triplet codons, 61 triplets are responsible for coding the amino acid whereas three of them form a stop codon that helps terminate the translation.
