Question

To initiate translation, the mRNA first binds to

• A. No such specificity exists
• B. The smaller ribosomal sub-unit
• C. The larger ribosomal sub-unit
• D. The whole ribosome

Answer 1

The correct option is B

The smaller ribosomal sub-unit

The first step of the initiation stage of translation is the binding of mRNA to the small ribosomal subunit through base pairing with appropriate sequences on rRNA.
