I think the answer is (2)RNA polymerase. The process of transcription begins when an enzyme called RNA polymerase (RNA pol) attaches to the template DNA strand and begins to catalyze production of complementary RNA.

RNA Polymerase in Transcription:
RNA polymerase is the correct answer for the enzyme that facilitates the opening of the DNA helix during transcription. Here is an explanation of how RNA polymerase functions in this process:
Transcription Process:
- Transcription is the process by which RNA is synthesized from a DNA template.
- During transcription, RNA polymerase binds to a specific region of DNA called the promoter.
- RNA polymerase helps to unwind the DNA double helix, allowing for the formation of an RNA strand.
- As RNA polymerase moves along the DNA template, it synthesizes an RNA molecule that is complementary to the DNA template.
- Once transcription is complete, the RNA polymerase releases the newly synthesized RNA molecule.
Role of RNA Polymerase:
- RNA polymerase plays a crucial role in transcription by facilitating the opening of the DNA helix and synthesizing RNA from the DNA template.
- It acts as a molecular motor that moves along the DNA template and catalyzes the formation of phosphodiester bonds between nucleotides to form the RNA strand.
- RNA polymerase also helps in proofreading and editing the newly synthesized RNA molecule.
In conclusion, RNA polymerase is the enzyme responsible for opening the DNA helix during transcription and synthesizing RNA from a DNA template. It plays a vital role in the process of gene expression and is essential for the production of proteins in cells.
