Question 11 • CR03051B Biology

Which statement best compares transcription and translation?

Answer
A
tRNA pairs with complementary mRNA in both transcription and translation.
B
A peptide bond is created between amino acids in both transcription and translation.
C
DNA is transcribed into a complementary strand of mRNA in translation but not transcription.
D
A chain of amino acids linked by peptide bonds is formed in translation but not transcription.

Explanation

Translation uses the information in mRNA to join amino acids into a chain, forming peptide bonds. Transcription copies DNA into RNA; it does not build a chain of amino acids. Therefore, the statement that an amino-acid chain is formed in translation but not transcription is correct.
