Molecular Processes: DNA Replication, Transcription, and Repair

Molecular processes are the engine of life, determining how genetic code is maintained, utilized, and passed on to subsequent generations. This course provides a comprehensive, text-based introduction to the core processes of molecular biology. You will gain a deep understanding of how DNA is duplicated, transcribed into RNA, and translated into proteins, along with the crucial regulatory systems that govern these steps in both prokaryotes and eukaryotes. By the end of this course, you will have a clear, foundational grasp of the central dogma and genomic maintenance. What you'll learn: * Understand the mechanics of DNA replication, including the roles of key enzymes and proofreading mechanisms. * Master the stages of gene transcription and the differences between prokaryotic and eukaryotic RNA polymerases. * Apply the principles of translation to decipher how messenger RNA is converted into functional proteins. * Analyze fundamental mechanisms of gene regulation, including operons and transcription factor activity. * Learn basic concepts of DNA repair pathways that maintain genomic integrity against damage. * Explore the foundational regulatory roles of non-coding RNAs in controlling gene expression. We begin with the structure of nucleic acids and foundational concepts, moving sequentially through DNA replication, repair, transcription, and translation. The course concludes with an examination of how these processes are tightly controlled and regulated within the cell. This course is designed for absolute beginners, students new to molecular biology, or anyone seeking a solid, detailed written explanation of cellular fundamental processes. No prior knowledge of genetics or biology is required. Start building your foundational knowledge of life's fundamental molecular machinery today.
