Multiple Choice
The direction of ribosome movement during translation is in the ______________.
A
3' → 5' direction of DNA.
B
5' → 3' direction of tRNA.
C
3' → 5' direction of mRNA.
D
5' → 3' direction of mRNA.
Verified step by step guidance
1
Understand that translation is the process by which ribosomes synthesize proteins using mRNA as a template.
Recall that mRNA is synthesized in the 5' to 3' direction during transcription, and this orientation is crucial for translation.
Recognize that during translation, ribosomes read the mRNA sequence in the 5' to 3' direction to ensure the correct sequence of amino acids is added to the growing polypeptide chain.
Consider the options given: 3' → 5' direction of DNA, 5' → 3' direction of tRNA, and 3' → 5' direction of mRNA. Note that these do not align with the known process of translation.
Conclude that the correct direction of ribosome movement during translation is the 5' → 3' direction of mRNA, as this is how the ribosome reads the mRNA to synthesize proteins.
