Molecular Biology Foundations: DNA Replication and Repair

Understanding molecular biology is essential for anyone pursuing a career in life sciences, biotechnology, or preparing for rigorous academic examinations. This text-based course breaks down the complex, microscopic processes of genetic preservation and transmission into clear, manageable concepts. You will begin with foundational molecular structures before exploring the precise mechanics that keep genomes stable across generations. By the end of this course, you will have a comprehensive grasp of how genetic material duplicates and corrects itself, enabling you to solve complex biological problems with confidence. What you will learn: Understand the structural components of DNA and the fundamental rules of nucleic acid chemistry; Analyze the step-by-step process of DNA replication in both prokaryotes and eukaryotes; Identify key replication enzymes including polymerases, helicases, and ligases, along with their specific functions; Explore cellular proofreading and repair mechanisms that prevent mutations and maintain genomic integrity; Apply molecular biology principles to analyze experimental scenarios and standardized exam questions. The course begins with core terminology and structural biochemistry before progressing systematically through initiation, elongation, termination, and post-replication repair pathways. This course is designed specifically for beginners, undergraduate students, and exam aspirants with a basic background in biology, requiring no advanced prior knowledge of molecular genetics.
