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.
Explanation / Answer
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.
