Suppose evolution on earth had occurred in such a way that there are 96amino acid instead of 20.dna has 12 different types of bases and synthesis occur in same way as today, then the minimum no bases per DNA codon would be? a-12,b-8,c-2,d-3
If one base is one codon and it codes one amino acid, then (12)1 = 12 amino acids.
But we have 96 amino acids.
Suppose two bases form one codon, then (12)² = 144 amino acids.
Thus, if two bases form one codon, it is sufficient to code 96 or 20 amino acids.
Hence, the minimum number of bases per DNA codon should be 2.
