Assume that the number of different types of bases in RNA is four. What would be the minimum codon size (number of nucleotides) required to specify all amino acids if the number of different types of amino acids in proteins were:

The complete question is:

What would be the minimum codon size (number of nucleotides) required to specify all amino acids if the number of different types of amino acids in proteins were: (1) 2, (2) 8, (3) 17, (4) 45, (5) 75?

Answers:

1) 1

2) 2

3) 3

4) 3

5) 4

These calculation take into account:

Available bases^ codon size

( * nucleotides) = * possible codons
