Question

Which of the following is not correct about translation?

• A. It starts with AUG.
• B. It stopped at termination codon.
• C. The conversion of codon information into proteins is conducted by transfer RNA.
• D. It occurs in nucleus.

Answer 1

Answer: (D)

It occurs in nucleus.

A. Translation starts with the start codon AUG that also codes for methionine.

B. Translation stops when a stop codon is encountered. There are three stop codons UAA, UAG OR UGA.

C. Amino acids are transferred to transfer RNA or tRNA and during the process of transfer, a high energy ester bond is formed between the carboxyl group of amino acid and 3'- hydroxy group of terminal adenosine of tRNA.

D. Translation occurs in cytoplasm in both prokaryotes and eukaryotes.

Hence, statement D is incorrect. So, the correct answer is 'It occurs in nucleus'.
