Question

Answer

RNA Polymerase

RNA polymerase is an enzyme that is responsible for the synthesis of RNA from a DNA template during the process of transcription.

It binds to the promoter region of the DNA and initiates the process of transcription.

RNA polymerase reads the DNA template strand in the 3' to 5' direction and synthesizes the RNA strand in the 5' to 3' direction.

During transcription, RNA polymerase unwinds the DNA double helix and separates the two strands.

It then uses one of the DNA strands as a template to synthesize a complementary RNA molecule.

RNA polymerase adds nucleotides to the growing RNA chain by forming phosphodiester bonds between the 3' end of the RNA molecule and the 5' end of the incoming nucleotide.

Once the RNA polymerase has synthesized the RNA molecule, it dissociates from the DNA template strand and the RNA molecule is released.

Answer

The RNA polymerase binds to the promoter region of the DNA molecule. After the attachment of the RNA polymerase enzyme to the promoter, the process of transcription is being initiated.
