The Initiation Complex Moves in Which Direction Along the MRNA

Question

The initiation complex moves in which direction along the mRNA molecule?
A) 5' ® 3'
B) 3' ® 5'
C) 1'® 4'
D) 5' ® 3' and 3' ® 5'
E) None of these

Accepted Answer

The initiation complex moves along the mRNA molecule in the 5' to 3' direction, meaning it moves towards the 3' end of the mRNA molecule. This is because translation always occurs in this direction on the mRNA template.
