c) sigma
d) all of these
Which of the following subunit/s of RNA polymerase is/are required for RNA polymerase to bind to the promoter?
a) beta
b) sigma factor

In which of the following activity/ies, RNA polymerase is different from DNA polymerase?
a) it adds nucleotides to 3’ end
b) direction of polymerization is from 5’ to 3’ end
c) it does not require primer to perform polymerization
d) all of these
How many RNA polymerase enzyme/s is/are found in prokaryotes?
a) two
b) three
c) four
d) one
Explanation: both prokaryotic and eukaryotic transcriptions require the same enzyme, RNA polymerase. For all types of RNA transcription, prokaryotes use a single RNA polymerase.

d) one
Explanation: RNA polymerase-I, RNA polymerase-II and RNA polymerase-III
Which of the following RNA polymerase synthesize/s rRNA in eukaryotes?
