Study Notes

DNA Replication

Each strand of the original DNA molecule serves as a template for the production of its counterpart during DNA replication.
The purpose of DNA replication is to create an exact copy of the original DNA molecule, allowing genetic information to be passed on to daughter cells.

Structure of DNA

DNA is a double-stranded molecule, consisting of two complementary strands of nucleotides that are twisted together in a double helix structure.

Importance of DNA Replication

DNA replication is essential for cell division, as it allows the genetic material to be duplicated and distributed evenly between daughter cells.

Process of DNA Replication

Each strand of the original DNA molecule serves as a template for the production of its counterpart, a process referred to as semi-conservative replication.
The enzyme helicase separates the double-stranded DNA during replication.
Primers bind to each separated strand of DNA during replication.
The enzyme primase adds in the primer during DNA replication.
Elongation occurs in the 5' to 3' direction during DNA replication.
DNA polymerase replaces the RNA primer during DNA replication.
