The mRNA consisting of 282 nucleotides can produce a polypeptide chain of
View answer and explanation
Correct option: C
93 amino acids
Option D (94 amino acids) is incorrect. The correct answer is 93 amino acids because the mRNA consists of 282 nucleotides, and each codon consists of 3 nucleotides. Therefore, 282 / 3 = 94 codons. However, one codon is a stop codon, so 94 - 1 = 93 amino acids.
