What is the definition of DNA replication?

The definition of DNA replication is best described as a natural process of making a copy of DNA. This fundamental biological process ensures that when a cell divides, each new cell receives an identical copy of the DNA, preserving genetic information. DNA replication involves unwinding the double helix structure, separating the two strands, and synthesizing new complementary strands using the original strands as templates. This seamless copying mechanism is critical for growth, development, and maintenance of all living organisms.

While sequencing DNA, amplifying it, and breaking hydrogen bonds are relevant molecular biology techniques, they do not capture the essence of replication as a natural process aimed specifically at duplicating DNA for cell division and ensuring genetic continuity.
