The tertiary complex required for prokaryotic initiation of translation includes:

a. mRNA, small ribosomal subunit, f-Met-tRNAi.

b. mRNA, small ribosomal subunit, large ribosomal subunit.

c. mRNA, large ribosomal subunit, f-Met-tRNAi.

d. mRNA, small ribosomal subunit, helicase.

e. none of the above

Solutions

Expert Solution

The translation process requires mRNA, rRNA, ribosomes, 20 kinds of amino acids and their specific tRNAs.

Initiation involves the small subunit of the ribosome binding to the 5' end of mRNA with the help of initiation factors (IF), In prokaryotes, starting amino acid is N-formyl methionine.

So, option a (mRNA, small ribosomal subunit, f-Met-tRNAi) is the correct answer.
