What happens right before transcription begins?

RNA polymerase enzyme bind to the promoter sequence of the gene

Explanation:

In the process of transcription, the DNA sequences of a gene are copied to produce RNA molecule by RNA polymerase enzyme.

For the initiation of transcription, the enzyme – RNA polymerase must bind to the promoter sequence of the gene either directly or through some helper protein. One of the DNA strands is used as the template for making complementary RNA molecule
