44. The consensus sequence 5² TATAAAA 3² found in eukaryotic genes is quite similar to a consensus sequence observed in prokaryotes. It is impor¬tant as the
a. Only site of binding of RNA polymerase III
b. Promoter for all RNA polymerases
c. Termination site for RNA polymerase II
d. Major binding site of RNA polymerase I
e. First site of binding of a transcription factor for RNA polymerase II
45. The so-called caps of RNA molecules
a. Allow tRNA to be processed
b. Occur at the 3² end of tRNA
c. Are composed of poly A
d. Are unique to eukaryotic mRNA
e. Allow correct translation of prokaryotic mRNA
