Given this, what advantage might be offered by having a code with 64 codons?

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

Explanation / Answer

There are 20 amino acids but there are 64 codons, out of which 61 code for amino acids and 3 code for stop codons. This phenomenon is called redundancy. This is a measure to tolerate errors in nucleotide sequence. that is small changes in amino acid codons will not have greater effects on protein synthesis because of this redundancy.

For example

Proline is coded by CCU, CCC, CCA, CCG. if there is a change from U>C or A>G even then amino acid will not change, it will remain as proline only.

So the answer is

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