A minimal genetic code requires only 21 codonsone for each a

A minimal genetic code requires only 21 codons-one for each amino acid, and one for a stop signal Given this, what advantage m: gate offered by having a code with 64 codons? An advantage of having more than the minimum number of codons is error tolerance Because of the redundancy in an expanded code not every base pair change will change the meaning of a codon. An advantage of having more than the minimum number of codons is evident Because more number of codons makes an amino acid sequence more varied that influences on the function of this protein. An advantage of having more than the minimum number of codons is doubtful Because on me one hand it makes possible to code more amino acids but on me other hand mistakes during translation are happening more often

Solution

An advantage of having more than the minimum number of codons is error tolerance. Because of the redundancy in an expanded code, not every base pair change the meaning of a codon.
