What is the process by which DNA copies itself?
Answer
DNA replication
DNA replication is the biochemical process by which DNA produces an identical duplicate of itself using semi-conservative replication. The DNA double helix unwinds, and each strand serves as a template for synthesizing a new complementary strand using DNA polymerase enzyme. DNA replication occurs before cell division to ensure each daughter cell receives a complete copy of genetic information. The Meselson-Stahl experiment elegantly demonstrated the semi-conservative mechanism. Errors during replication are corrected by proofreading enzymes, making DNA replication one of biology's most accurate molecular processes.
💡 Did you know?
DNA replication is astonishingly accurate: only 1 error in 10 billion nucleotides, thanks to multiple proofreading mechanisms.
