DNA Replication: Molecular Mechanisms and Biological Significance

This course provides a comprehensive introduction to DNA replication, a fundamental process in molecular biology and genetics. Learners will explore the semi-conservative nature of DNA replication, the role of key enzymes such as DNA polymerases, helicase, primase, and ligase, and molecular events occurring at the replication fork. The course also highlights differences between prokaryotic and eukaryotic DNA replication and emphasizes the biological and clinical significance of replication fidelity and errors.​

About Course

The DNA Replication: Molecular Mechanisms and Biological Significance course provides learners with a thorough understanding of one of the most essential processes in molecular biology and genetics. The course examines the semi-conservative nature of DNA replication and the coordinated action of key enzymes involved in DNA synthesis, including DNA polymerases, helicase, primase, and ligase.

Students will explore the molecular events occurring at the replication fork and compare replication mechanisms in prokaryotic and eukaryotic systems. Emphasis is placed on replication accuracy, regulatory mechanisms, and the biological and clinical consequences of replication errors, building a strong foundation for advanced studies in genetics, biotechnology, and biomedical sciences.
