Fundamentals of Genetic Mutation and Genome Stability

Mutation is the engine of evolution and the cause of many diseases. Start your journey into molecular biology by understanding how errors and changes occur in the foundational genetic code. By the end of this course, you will have a solid foundational understanding of DNA mutation, covering everything from simple point mutations to large-scale chromosomal aberrations. You will be able to analyze the molecular events that lead to changes in the genome and the complex cellular systems responsible for detecting and fixing them, ensuring genome stability. What you'll learn: * Understand the core definitions and classification systems for various types of genetic mutations (point, silent, missense, nonsense, frameshift). * Analyze the causes of mutation, including physical and chemical mutagens and intrinsic errors during DNA replication. * Master the steps and components of major DNA repair pathways, such as Nucleotide Excision Repair (NER) and Mismatch Repair (MMR). * Apply knowledge of mutation effects to understand their role in human genetic disorders and evolutionary change. * Learn basic concepts for detecting and analyzing mutations using modern molecular techniques. The course begins with terminology and molecular structure, proceeds through the mechanisms by which mutations are generated and classified, and culminates in a detailed examination of the sophisticated DNA repair systems that maintain genome integrity. All concepts are explained clearly through written examples and foundational molecular principles. This introductory course is designed for absolute beginners in molecular biology, genetics, or biochemistry. No prior knowledge of molecular genetics is required; we start with the fundamentals.
