Introduction to DNA Replication
DNA replication is the biological process through which a cell duplicates its DNA, ensuring each daughter cell inherits an identical copy of genetic information during cell division. This process is essential for growth, development, and tissue repair in all living organisms.
Key points about DNA replication:
- It is semi-conservative, meaning each new DNA molecule consists of one original (template) strand and one newly synthesized strand.
- It occurs during the S-phase of the cell cycle.
- The process involves multiple enzymes, including DNA helicase, DNA polymerase, and ligase.
Understanding these fundamental concepts is crucial for biology students, and practice worksheets with answer keys are excellent tools for reinforcing this knowledge.
