DNA replication is the process where the two strands of a DNA double helix separate, allowing each strand to serve as a template for synthesizing a complementary strand through specific base pairing. This process includes autonomous replication but excludes viral replication.DNA replication is the process where the two strands of a DNA double helix separate, allowing each strand to serve as a template for synthesizing a complementary strand through specific base pairing.
