the process of copying dna is called
The process of copying DNA is called DNA replication.
What DNA replication means
DNA replication is the biological process in which a cell makes an exact copy of its DNA before it divides, so each new cell gets the same genetic information.
- It produces two identical DNA molecules from one original molecule.
- It happens in virtually all living organisms as the basis of genetic inheritance.
How the process works (simple view)
You can imagine DNA replication like unzipping a zipper and rebuilding the missing teeth on each side.
- The DNA double helix unwinds and “unzips” at specific start points called origins of replication.
- Each original strand acts as a template for making a new complementary strand, following base‑pair rules (A with T, C with G).
- Enzymes called DNA polymerases add new nucleotides to build the new strands and proofread to correct many errors.
- Other enzymes join DNA fragments and seal the backbone, producing two complete double‑stranded DNA molecules.
Because each new molecule keeps one old strand and one new strand, DNA replication is described as semiconservative.
Why DNA replication matters now
DNA replication is central to:
- Cell division and growth: every time cells divide, they must replicate DNA accurately.
- Inheritance: faithful copying lets organisms pass traits to offspring.
- Biotechnology: many lab methods, like PCR, are built on controlled DNA copying for tests, forensics, and research.
In short, when you see the phrase “the process of copying DNA is called…” , the precise term you’re looking for is DNA replication.
