Study Notes
DNA Replication Overview
- DNA replication produces two identical DNA replicas from one original molecule.
- Essential for biological inheritance, occurring in all living organisms.
Process of DNA Replication
- Initiates at specific locations called origins of replication within the genome.
- Unwinding of DNA accomplished by helicase, an enzyme that forms replication forks.
- Replication forks grow bi-directionally from the origin.
Role of Proteins in Replication
- Various proteins associate with the replication fork to facilitate DNA synthesis.
- DNA polymerase is the key enzyme that synthesizes new DNA strands.
- DNA polymerase adds nucleotides that are complementary to the template strands.
Timing of DNA Replication
- DNA replication occurs during the S (synthesis) stage of Interphase.
