WebDNA dependent RNA polymerase somehow also facilitates opening of helix and continues elongation. It uses nucleoside triphosphates as substrate and polymerises in a template depended fashion following the rule of complementarity. DNA helicase unwind the DNA helix and unzips the the two strands. WebThe enzyme DNA helicase breaks the hydrogen bonds between the bases in a specific region of the DNA molecule. This causes the two strands to separate and unwind, exposing nucleotide bases. The enzyme RNA polymerase binds to the template strand of DNA at the beginning of the sequence to be copied.
