Enzymes involved in Replication for IIT JAM Biotechnology / GAT B / CUET PG 2025 | Molecular Biology
IIT JAM Biotechnology , GAT B , CUET PG & TIFR・2 minutes read
A lecture series on Molecular Biology is starting, covering topics like DNA replication, DNA polymerase, and cell division mechanisms. The focus is on understanding key processes and preparing for upcoming sessions, including a practice session with Mohit Sir in the evening.
Insights
- DNA replication involves a template-dependent process where DNA polymerase synthesizes in the 5' to 3' direction, removing two phosphates and adding one phosphate, resulting in semi-continuous synthesis.
- Meselson and Stahl's experiment confirmed the semi-conservative nature of DNA replication by using N15 and N14 isotopes, showing that one parental strand remains in each new DNA molecule.

Recent questions
What is the central dogma?
The central dogma refers to the flow of genetic information from DNA to RNA to protein.
Why is DNA replication important?
DNA replication is crucial for cell division and passing genetic information to offspring.
What are the phases of cell division?
Cell division involves phases like prophase, metaphase, anaphase, and telophase.
What is the role of DNA polymerase?
DNA polymerase is responsible for synthesizing new DNA strands during replication.
What did Meselson and Stahl's experiment prove?
Meselson and Stahl's experiment confirmed the semi-conservative nature of DNA replication.
