Question

This could account for Blank. Since one Blank can bind to several Blank, there is an advantage for all those codons to code for the same amino acid.

Answer 1

Evolutionary accidents (mutations) that modified the third nucleotide base in the codon might have been selected for if they coded for the same amino acid because of the selective advantage of having to make fewer errors. This could account for genetic redundancy. Since one tRNA can bind to several codons, there is an advantage for all those codons to code for the same amino acid.
