Verified
Initiation, elongation, and termination are three stages in
A) DNA replication.
B) error correction by proofreading enzymes.
C) mRNA processing.
D) translation.
E) intron removal.
Initiation
First stage of translation in which the translational machinery binds an mRNA and assembles.
Elongation
Middle stage of translation in which additional amino acids specified by the mRNA are added to the growing polypeptide.
Termination
End of translation that occurs when a ribosome reaches a stop codon on the mRNA that it is translating, causing release of the completed protein.

Final Answer :
D
Explanation :
Initiation, elongation, and termination are stages in translation, the process by which mRNA is used as a template to synthesize protein. During initiation, the ribosome assembles on the mRNA and the first amino acid is brought in by a tRNA. Elongation involves the addition of amino acids to the growing peptide chain, and termination occurs when a stop codon is reached and the assembled protein is released from the ribosome. DNA replication involves different stages, while mRNA processing involves steps such as splicing and capping, and error correction by proofreading enzymes occurs during DNA replication and DNA transcription.
