Explanation / Answer

The structure for the question 1 is missing , so let me help you with the next one ...

Ans 2 :c) A set of 3 bases that call for a specific amino acid

The codons are the set of three nucleotides or bases which form the basis of the genetic code in DNA or RNA . These codons have specific amino acid and they are unambiguous as each one of it calls for a single amino acid only.
