Foundations of DNA Repair

Errors in DNA can have profound consequences for cellular function and organismal health. This course will equip you with a foundational understanding of the intricate mechanisms cells employ to detect, identify, and repair various types of DNA damage, ensuring genomic stability. What you'll learn: * Understand the different types of DNA damage and their origins * Learn the major DNA repair pathways, including direct repair, base excision repair, nucleotide excision repair, mismatch repair, and double-strand break repair * Apply knowledge of repair mechanisms to recognize their roles in maintaining genomic integrity * Analyze the cellular consequences of ineffective DNA repair, including its links to disease and aging * Grasp the basic principles of the DNA damage response and its regulatory checkpoints The course begins with an exploration of DNA damage sources, then systematically covers each major repair pathway, detailing the steps and key enzymes involved. It progresses from fundamental concepts of DNA damage to the sophisticated cellular machinery that corrects these errors, concluding with the broader implications of repair deficiencies. This course is designed for absolute beginners in molecular biology, genetics, or biochemistry with no prior knowledge of DNA repair mechanisms. No prerequisites are required; all foundational concepts will be explained. Begin your journey into the fascinating world of cellular self-preservation.
