Q. Statement I: There is single DNA-dependent RNA polymerase that catalyses transcription of all types of RNA (mRNA, tRNA and rRNA) in eukaryotes
Statement II : In bacteria, at least three RNA polymerases are required.

Molecular Basis of Inheritance

Solution:

• There is single DNA-dependent RNA polymerase that catalyses transcription of all types of RNA in bacteria.
• In eukaryotes, there are at least three RNA polymerases in the nucleus (in addition to the RNA polymerase found in the organelles).
