7. In a laboratory, a scientist wanted to study the structure and functions of RNA polymerase I, II and III. He know that RNA polymerase II is most studied and synthesizes mRNA and some other small RNAs and the RNAs which are integral part of ribosomes are formed by RNA polymerase I but while his experiments he did not get 5 S rRNA from RNA polymerase I.

On the basis of above paragraph answer the following questions:
The most probable reason for not getting 5 S rRNA from RNA polymerase I is
(1) During the experiment RNA polymerase I gets mutatedand unable to code 5 S rRNA.
(2) As rRNA is smaller RNA, we cannot extract it experimentally
(3) It is synthesized by different RNA polymerase that also codes for tRNA
(4) It is soluble RNA so readily solubilizes in the solution

Which of the given is the most probable source taken by him for his experiments?
(1)Nostoc
(2)Aspergillus
(3)Rhizobium
(4)E. coli
