Basic Principles of DNA Replication

• LIGases: seal the gaps between the new and old DNA strands

At its core, DNA replication is the process by which a cell makes an exact copy of its DNA before cell division. This is an essential process for growth, repair, and allowing cells to function correctly. Key to this process are enzymes, specifically those found in the replication machinery. They work together to unwind the double helix structure of DNA, create a replicate strand, and modify the original DNA template. Think of enzymes as specialized tools that help untangle and synthesize exact copies of the genetic code.

• Helicases: unwind the double helix
• DNA polymerase: acts as the primary catalyst in assembling new DNA strands
