본문내용

Definition: The synthesis of RNA from a DNA template is carried out by enzymes known formally as DNA-dependent RNA polymerases.

1. Precursors ; 5’-triphosphates(rNTPs) A, G,C, U
2. The 3’-OH terminus reacts 5’-triphosphate of a precursor rNTPs
3. 5’3’ directions
4. Base pairing C::G, T::A, G::C, A::U
5. Selective Process : sense strand and antisense strand
6. RNA polymerase // No primer is needed!
7. Only ribonucleoside 5’-triphosphates participate in RNA synthesis, and the first base to be laid down in the initiation event retains its triphosphate.
