DNA Replication, definition, procedure, steps, features, significance

DNA replication is the method by which a double-stranded DNA molecule is copied to generate two identical DNA molecules.

Replication is a fundamental process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.

The replication process relies on the fact that each strand of DNA can serve as a template for duplication.

DNA replication initiates at specific points, called origins, where the DNA double helix is unwound. A short segment of RNA, called a primer, is then synthesized and acts as a starting point for new DNA synthesis.

An enzyme called DNA polymerase next begins replicating the DNA by matching bases to the original strand.

Once synthesis is complete, the RNA primers are replaced with DNA, and any gaps between newly synthesized DNA segments are sealed together with enzymes.

DNA replication is a crucial process; therefore, to ensure that mistakes, or mutations, are not introduced, the cell proofreads the newly synthesized DNA.

Once the DNA in a cell is replicated, the cell can divide into two cells, each of which has an identical copy of the original DNA.
