MCQ
If genetic code is tetraplet then what is the possible number of codons which code 20 types of amino acids?
- A261
- B64
- C256
- D43
Explanation:
At any given position in a nucleic acid, there are four possible nucleotides which can occur. There are two nucleotides containing purine bases and two containing pyrimidine bases.
If the genetic codon is tetraplet, there will be 4 × 4 × 4 × 4 or 256 possible codons to code for 20 amino acids.
