What would be the number of nucleotides for a protein molecule of about 142 amino acids?
Correct answer: C. 426
- A. 430
- B. 142
- C. 426
- D. 460
Explanation
Each amino acid is coded by 3 nucleotides, hence to form a protein molecule of 142 amino acids, 142 multiplied by 3 nucleotides would be needed, which comes out to be 426.
