Web26 jul. 2024 · Hydrogen bonds between base pairs break which allows the unzipping of the double helix. As RNA polymerase breaks the bonds, it synthesises a primary transcript of mRNA using RNA nucleotides. WebHydrogen bonds form when hydrogen atoms covalently bonded to nitrogen (N), oxygen (O), or fluorine (F) in the form of covalent compounds such as ammonia (NH 3), water (H 2 O) and hydrogen fluoride gas (HF). In these molecules, the hydrogen atoms do not pull as strongly on the shared electrons as the N, O, or F atoms.
