Answer:
Step-by-step explanation:
tRNA, or transfer RNA, plays an essential role in the process of protein synthesis (creation).
After DNA is transcripted and translated, the messenger RNA is created in the nucleus and sent to the ribosome. The mRNA has codons or sets of three nucleotides. Then, the tRNA enters. The tRNA has an amino acid (the monomer of proteins) and an anticodon (three nucleotides that are complementary to the mRNA).
The codon and anticodon create base pairs, and the amino acids attach to form a protein.
Based on this information, the best answer choice is A. bring an amino acid to the ribosome
