The Correct Option is C
Solution and Explanation
Step 1: The genetic code has 64 possible codons formed from combinations of the 4 bases taken three at a time.
Step 2: Out of these, 61 codons code for the 20 standard amino acids, showing the redundancy of the genetic code.
Step 3: The remaining 3 codons, UAA, UAG and UGA, do not code for any amino acid, they act as stop or termination codons that end translation.
Step 4: So 3 codons do not specify amino acids.
