Secondary downstream of the cap structure in the mRNA is unwound during the __________ step of translation.
A) initiation
B) elongation
C) translocation
D) termination

Question

Quizplus · Accepted Answer

During the initiation step of translation, the small ribosomal subunit binds to the cap structure at the 5' end of the mRNA and scans downstream until it reaches the start codon. At this point, the large ribosomal subunit joins the complex and the secondary structure downstream of the start codon is unwound, allowing for the proper alignment of the tRNA and the ribosome during protein synthesis.
