Question

1.) Answer the following true/false

A.) T/F Like the promoter, the ribosome binding site (RBS) is a DNA sequence that is not transcribed.

B.) T/F Loss-of-function point mutations in the RBS may be suppressed by point mutations in the 16S rRNA.

C.) T/F Each ribosome has two subunits (large and small) which eventually come apart and partner up with subunits from other ribosomes.

D.) T/F All aminoacyl-tRNAs enter the ribosome via the A site.

E.) T/F The growing polypeptide is always attached to the tRNA in the P site.

Answer 1

A.) T/F Like the promoter, the ribosome binding site (RBS) is a DNA sequence that is not transcribed.
THE ANSWER IS FALSE.

B.) T/F Loss-of-function point mutations in the RBS may be suppressed by point mutations in the 16S rRNA.
THE ANSWER IS TRUE.

C.) T/F Each ribosome has two subunits (large and small) which eventually come apart and partner up with subunits from other ribosomes.
THE ANSWER IS TRUE.

D.) T/F All aminoacyl-tRNAs enter the ribosome via the A site.
THE ANSWER IS FALSE. THE FIRST AMINO ACIDS ENTERS IN TO P SITE.

E.) T/F The growing polypeptide is always attached to the tRNA in the P site.
THE ANSWER IS TRUE. BECUASE PEPTIDYL TRANSFEREASE IS NEEDED FOR PEPTIDE BOND FORMATION, WHICH IS PRESENT IN P SITE.
