Question

To initiate translation, the mRNA first binds to:

• A. The large ribosomal subunit
• B. The whole ribosome
• C. No such specificity exists
• D. The small ribosomal subunit

Answer 1

The correct option is D The small ribosomal subunit

$Initiationoftranslation$

First, the mRNA binds with the small ribosomal subunit.

Then the mRNA-smaller subunit complex binds with the tRNA containing methionine. After that the larger subunit binds.

These processes take place during initiation of translation.

Hence, the correct answer is option a, the small ribosomal subunit.
