1. RNA polymerase attaches to DNA. This causes hydrogenm bonds to break meaning the DNA unzips and uncoilds seperating the two strands. One strand used as a template.
2. Activated RNA free nucleotides binds with hydrogen bonds, to their exposed complemetary bases.
3. Two extra phosphates are released producing energy for bonding adjacent nucleotides.
4. RNA polymerase moves along assemblying the mRNA, the hydrogen bonds between the DNA strands reform once rna polymerase has passed.
5. when rna polymerase reaches stop codon it stops making mRNA and detached from the DNA
6. the mRNA moves out of the nucleus through nuclear pores and attaches to a ribosome in the cytoplasm.
