• termination, elongation, initiation

• initiation, elongation, termination

Answer 1

The correct sequence of events in the production of a polypeptide is initiation, elongation, and termination.

Explanation:

The production of a polypeptide, or translation, occurs in a specific three-step sequence similar to a story with a beginning, middle, and end. It begins with initiation, where the ribosome assembles around the mRNA and the first tRNA molecule to start the process. This is followed by elongation, the stage where the chain actually “elongates” as the ribosome moves along the mRNA, reading codons and linking amino acids together with peptide bonds. Finally, the process reaches termination when a stop codon is encountered, signalling the ribosome to release the finished polypeptide and disassemble.
