What is the process by which DNA makes a copy of itself called?
- A. Replication
- B. Transcription
- C. Translation
- D. Polymerization
Answer: A. Replication
Replication is the biological process by which a double stranded DNA makes an exact copy of itself. This is crucial for cell division and growth, ensuring each daughter cell receives a complete set of genetic instructions. DNA replication is one of the most basic processes that occurs within a cell. DNA replication (duplication of DNA) occurs during the S phase of the cell cycle.
