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

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.

Select the statement which best summarizes the initiation of translation. The large ribosomal subunit binds to the mRNA first and the small subunit binds last The small ribosomal subunit binds to the mRNA first and the large subunit binds last Both subunits of the ribosome bind to the mRNA simultaneously There is no large ribosomal subunit, only a small subunit

8. Which of the following describes the initiation of bacterial transcription A. The small ribosomal subunit binds to the Shine-Dalgarno sequence B. The sigma factor binds at the -10 location C. Transcription begins at the +1 site which is always the start codon D. RNA polymerase disassociates with the sigma factor as it begins adding nucleotides at the 3’ end

Why is the sequence of the gene that codes the ribosomal small subunit so useful for microbial taxonomy? Cells without a functional ribosome cannot survive Ribosomal genes are often laterally transferred All of these reasons are true Cells without a functional ribosome cannot survive, and ribosomal gene sequences are highly conserved Ribosomal gene sequences are highly conserved
