Question

Select the incorrect statement.
a. Six codons do not code for any amino acid.
b. Codon reading of mRNA is contiguous.
c. Three codons function as stop codons.
d. Initiator codon AUG codes for methionine.

• A. a alone is incorrect
• B. a, b and d are incorrect
• C. a, b and c are incorrect
• D. b, c and d are incorrect
• E. b alone is incorrect

Answer 1

Answer: (A)

a alone is incorrect

A. a alone is incorrect

Solution : Codon reading of mRNA is contiguous and continuous. Three codons code for stopping the protein synthesis which are UAA, UAG and UGA. Initiator codon (AUG) codes for methionine.

So the correct answer is "a alone is incorrect".
