WebJul 5, 2024 · What does helicase do to the DNA ladder in transcription? Helicase is a group of enzyme that helps unwounds DNA by breaking hydrogen bonds between the nitrogenous bases. The last process is termination where a special DNA sequence in the template strand causes RNA polymerase to detach and transcription to terminate. WebInitiation is the beginning of transcription. It occurs when the enzyme RNA polymerase binds to a region of a gene called the promoter. This signals the DNA to unwind so the enzyme can ''read'' the bases in one of the DNA strands. The enzyme is now ready to make a strand of mRNA with a complementary sequence of bases.
