Final answer:
The component that enters the exit tunnel through the large subunit of the ribosome is the TRNA with attached lysine (#1).
Step-by-step explanation:
The component of the complex that enters the exit tunnel through the large subunit of the ribosome is the TRNA with attached lysine (#1).
The ribosome translation process is a fundamental step in protein synthesis, during which the information encoded in messenger RNA (mRNA) is used to assemble a corresponding polypeptide chain. Ribosomes, cellular structures composed of RNA and proteins, play a central role in this process. The translation process occurs in three main stages: initiation, elongation, and termination.
