Question 5 • Biology

Which is not something that occurs in translation?

Answer
A
A molecule of mRNA is formed.
B
A peptide bond is created.
C
An amino acid is added to a polypeptide.
D
A codon and an anticodon pair.

Explanation

Translation uses an existing mRNA molecule as a template; it does not form mRNA. During translation, a codon on the mRNA pairs with a tRNA anticodon, amino acids are added to the growing polypeptide, and peptide bonds join them. Therefore, “A molecule of mRNA is formed” is not something that occurs in translation.
