Answer 2

The enzyme which facilitates opening of DNA helix during transcription is (3) RNA polymerase.

RNA polymerase:

• RNA polymerase is from the eukaryote cells family. It is also called as Pol III.
• It is a macro molecular complex protein which transcribes DNA to synthesize ribosomal 5S rRNA, tRNA and other tiny RNAs.
• It facilitates starting or opening of DNA helix during transcription.
• It opens or takes out the double-stranded DNA to expose the DNA template to the active site or place.
• Hence, the correct answer is option (3) RNA polymerase.
