Question

Which statement correctly describes mRNA?
Options
A mRNA binds amino acids for incorporation into proteins
B mRNA contains the five-carbon sugar deoxyribose
C mRNA recognizes the anticodon of tRNA.
D None of the above
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

A: This is the function of tRNA, not mRNA. B: mRNA contains the sugar ribose, not deoxyribose. C: The codon on mRNA base-pairs with the anticodon on tRNA, but it is the tRNA that 'recognizes' the codon via its anticodon. The mRNA does not actively 'recognize' anything. Therefore, all statements are incorrect.

Hint

Review the specific roles of mRNA, tRNA, and rRNA.
