Answer
Brief Explanations:
Reverse transcriptase is an enzyme that catalyzes the formation of DNA from RNA. Among the options, mRNA (messenger - RNA) is used by reverse transcriptase to form DNA in a process called reverse transcription. Proteins are the end - products of translation, amino acids are the building blocks of proteins, and tRNA (transfer - RNA) is involved in translation by carrying amino acids to the ribosome.
