DNA, RNA, replication, translation, and transcription
DNA polymerase enzymes copy the open portions by forming the complementary strand. Nucleotide triphosphates are available in the cell.
Where does DNA Replication Begin?
The first step in DNA replication is the separation of the two strands by an enzyme called helicase. This spins the incoming DNA to unravel it at 10,000 rpm, in ...
