Answer:
AND
Step-by-step explanation:
D. They help in the transcription of proteins.
tRNA (transfer RNA) is a type of RNA molecule that functions in the process of protein synthesis (translation) by carrying a specific amino acid to the ribosome, where it will be added to the growing polypeptide chain. tRNA molecules contain an anticodon, which is a sequence of three nucleotides that recognizes and pairs with a complementary codon in the messenger RNA (mRNA) molecule during translation. tRNAs do not play a direct role in the transcription of DNA to mRNA, which is the first step in the synthesis of a protein.
