The rest of the genes that are not being expressed are silenced through folding by histones – so they are not exposed to DNA polymerase.
Adenosine triphosphate(ATP) transfer energy by doing phosphorylation. ATP has three phosphate molecule and it will release one phosphate when releasing energy(exergonic reaction), become ADP + P. ADP could be reused by catching energy(endergonic reaction), makes them catch a phosphate molecule and reform into ATP.
