Read the following statements and choose the correct opton.
I. RNA polymerase associates transiently with 'Rho' factor to initiate transcription.
II. In bacteria, transcription and translation takes place in the same compartment.
III. RNA polymerase I is responsible for transcription of t-RNA.
IV. When hn-RNA undergoes capping process, adenylate residues are added at 3' end in a template indepedent manner.
V. h-RNA is the precursor of m-RNA.

Options

A. only II
B. II, III and IV
C. III and IV
D. I and IV

Answer

D

Explanation

Out of the statements given I and V are the correct options, remaining three are wrong these can be corrected as in bacteria transcription and translation does not take place in the same compartments they are instead coupled in the cytosol itself as there is no sepration of nucleus and cytosol in bacteria therefore translation starts much before the mRNA is transcription of hnRNA polymerase I is responsible for the transcription of hnRNA (not tRNA)
When hnRNA undergoes capping process metyl guanosine triphosphate are added at 5' end in a template independent manner
