GENETICS

Lactose permease of E coli
is a protein composed of a single polypeptide that is 417 amino
acids in length. Amino acid residue 64 is the amino acid glycine
and aspartic acid is amino acid residue number 68.

Which of these amino acids is closer to the carboxyl terminus of
the polypeptide?

a)glycine

b)aspartic acid

Which of these amino acid’s codon is closer to the 3’ end of the
mRNA?

a)glycine

b)aspartic acid

5. Place the following events of translation in the order in
which they occur:

i. tRNAfMet binds in the P site

ii. RF2 binds in the A site

iii. EF-Tu helps tRNAPhe bind in the A site

iv. IF3 binds to the 30S ribosomal subunit

v. Peptide bond formation

vi. EF-G uses GTP to move the ribosome

vii. The 16S rRNA in the 30 S ribosomal subunit recognizes and
interacts with the Sine-Delgarno sequence in mRNA

viii. 50S subunit binds to 30S subunit
