Final answer:
The anticodon loop of the tRNA interacts with an mRNA codon during translation, ensuring correct amino acid sequence assembly.
Step-by-step explanation:
The loop of transfer RNA (tRNA) that interacts with the codon on messenger RNA (mRNA) in the translation process is called the anticodon loop. During translation, each tRNA molecule has an anticodon that is complementary to an mRNA codon. As the ribosome moves along the mRNA, it reads each codon and pairs it with the correct tRNA carrying an amino acid.
This tRNA's anticodon loop aligns opposite the mRNA codon, ensuring that the amino acids are added in the proper sequence to build the polypeptide chain.
