Study Notes
DNA Replication
- The process of DNA replication involves several enzymes, including helicase, primase, DNA polymerase, and ligase.
- During DNA replication, two identical daughter molecules are produced, each containing one old strand (the template) and one new strand synthesized during replication.
Cell Cycle
- In eukaryotic cells, DNA replication occurs during the S phase (synthesis phase) of the cell cycle.
Initiation of DNA Replication
- The initial step of DNA replication is the unwinding of the double helix at the origin of replication, mediated by the enzyme helicase.
Result of DNA Replication
- The result of DNA replication in eukaryotic cells is the production of two identical daughter DNA molecules, each with the same genetic information as the parent DNA molecule.
'Reading' Exposed Bases
- The enzyme responsible for 'reading' the exposed bases during DNA replication is DNA polymerase.
Purpose of DNA Replication
- The purpose of DNA replication is to ensure that each new cell receives a complete copy of the genetic material, essential for the transmission of genetic information from one generation to the next.
Template for DNA Replication
- The molecule that acts as a template for DNA replication is the original DNA molecule.
Cell Division
- Each time a cell divides, DNA replication occurs to ensure that the new cell receives a complete copy of the genetic material.

Description
Test your knowledge of DNA replication, a crucial process in the eukaryotic cell cycle where new DNA strands are built using complementary bases. Understand how two daughter molecules are formed, each containing one strand from the parent molecule and a new complementary strand.
