How do cells make accurate copies of DNA?

When a cell divides, it replicates its DNA by splitting apart double-stranded DNA Because the two strands of a DNA molecule have complementary base pairs, the nucleotide sequence of each strand automatically supplies the information needed to produce its partner and makes new copies

Explanation:

The process of making copies of DNA strand in nucleus of the cell is called replication. The cell divides into two and distributes each copy of DNA into the divided cells. Through replication the DNA transfers the information necessary for creating an exact copy of it in the new cell.
