Verified
The correct sequence of events in the production of a polypeptide is
A) initiation → termination → elongation.
B) elongation → termination → initiation.
C) termination → elongation → initiation.
D) elongation → initiation → termination.
E) initiation → elongation → termination.
Polypeptide Production
The process of synthesizing polypeptides, which are long chains of amino acids, through transcription and translation of genetic information.
Initiation
The start phase in various biological and chemical processes, such as the beginning of DNA replication or protein synthesis.
Elongation
In the context of protein synthesis, elongation is the stage during which amino acids are sequentially added to the growing polypeptide chain by the ribosome.

Final Answer :
E
Explanation :
The correct sequence of events in the production of a polypeptide is initiation, elongation, and termination. This process occurs during translation, where the mRNA is read by a ribosome, and amino acids are linked together to form a polypeptide chain. Initiation involves the binding of the ribosome to the mRNA and the start codon, while elongation involves the addition of amino acids to the growing polypeptide chain. Termination occurs when the ribosome reaches a stop codon and releases the completed polypeptide. Therefore, the correct sequence is initiation → elongation → termination.
