Understanding DNA: Structure, Replication, and Repair

DNA is the blueprint of life, yet its complex structure and processes can seem daunting to new students of biology. This course demystifies the molecular foundation of heredity. By the end of this course, you will have a solid foundational understanding of deoxyribonucleic acid, including its chemical composition, double helix structure, and the essential mechanisms required for life to function, such as accurate copying and damage correction. What you'll learn: * Understand the chemical composition of DNA, including nucleotides, bases, and phosphodiester linkages. * Master the double helix model and the rules governing base pairing (Chargaff's rules). * Analyze the process of DNA replication, including the roles of key enzymes and the semi-conservative model. * Apply knowledge of gene organization to understand how DNA is packaged into chromatin and chromosomes. * Learn the basic mechanisms cells use for DNA repair and damage correction to maintain genomic integrity. We begin with the basic terminology and chemical building blocks before examining the classic double helix structure. We then move into the functional processes of replication and organization within the nucleus. This course is designed for absolute beginners in molecular biology or genetics who need a firm grounding in the basics of DNA structure. No prior scientific knowledge is required.
