tRNA, rRNA and the Codon Code
Multiple Choice
In translation, what molecule directly delivers specific amino acids to the ribosome by matching its anticodon to an mRNA codon?
A
Ribosomal RNA (rRNA)
B
DNA polymerase
C
Transfer RNA (tRNA)
D
Messenger RNA (mRNA)
Verified step by step guidance1
Understand the process of translation, which is the synthesis of proteins from mRNA templates in the ribosome.
Recall that during translation, amino acids must be brought to the ribosome in the correct sequence dictated by the mRNA codons.
Identify the molecule responsible for delivering amino acids to the ribosome by recognizing specific codons on the mRNA through complementary base pairing with its anticodon.
Recognize that Transfer RNA (tRNA) has an anticodon region that pairs with the mRNA codon and carries the corresponding amino acid.
Conclude that tRNA is the molecule that directly delivers specific amino acids to the ribosome by matching its anticodon to an mRNA codon.
