If the codon consisted of only two nucleotides, there would be how many possible codons:
Correct answer: C. 16
- A. 4
- B. 8
- C. 16
- D. 20
Explanation
If a codon consisted of only two nucleotides, there would be 4 possible combinations for each position (since there are 4 different nucleotides: A, C, G, and T). Therefore, for a two-nucleotide codon, there would be 4 x 4 = 16 possible combinations. Therefore, option c is correct.
