Which of the following does not occur during translation's termination step?
A
The first tRNA brings the amino acid methionine to the ribosome.
B
The small and large ribosomal subunits separate from each other.
C
The polypeptide is released from the ribosome.
D
A "stop" codon is reached by the ribosome along the mRNA.
Verified step by step guidance1
Understand the process of translation in protein synthesis, which involves initiation, elongation, and termination phases.
During the termination phase of translation, the ribosome encounters a 'stop' codon on the mRNA, signaling the end of the polypeptide chain synthesis.
Recognize that the termination step involves the release of the newly synthesized polypeptide from the ribosome.
Identify that the small and large ribosomal subunits separate after the polypeptide is released, marking the end of translation.
Note that the first tRNA bringing methionine to the ribosome occurs during the initiation phase, not during termination, making it the correct answer to the question.
