Which answer choice matches the functions listed below to the correct RNA types?

(I.) Interprets a codon as an amino acid
(II.) Binds to a gene transcript
(III.) Contains information for assembling a protein


(A) I. mRNA; II. rRNA; III. tRNA
(B) I. mRNA; II. tRNA; III. rRNA
(C) I. rRNA; II. mRNA; III. tRNA
(D) I. tRNA; II. mRNA; III. rRNA
(E) I. tRNA; II. rRNA; III. mRNA
  1. Correct Answer: E


    Transfer RNA (tRNA) molecules carry amino acids and bind to specific mRNA codons. Ribosomal RNA (rRNA) makes up the ribosome and binds to the mRNA transcript. Messenger RNA (mRNA) carries genetic information from the nucleus to the cytoplasm.
