Question Detail
Question
Which statement correctly describes mRNA? 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
Option D is the correct answer.
Detailed Explanation
mRNA carries the genetic code from DNA to the ribosome. It contains ribose, not deoxyribose. It does not bind amino acids (tRNA does). It does not recognize anticodons; the ribosome facilitates the pairing between mRNA codons and tRNA anticodons. Therefore, none of A, B, or C are correct.
Hint
mRNA's job is to carry the message, not to carry amino acids or recognize other molecules directly.
