Introduction to DNA, Genes, and Molecular Inheritance

Molecular biology governs every aspect of life, yet its mechanisms often seem complex. This course demystifies the fundamental processes by which DNA carries information and directs the creation of proteins. By the end of this course, you will have a solid conceptual understanding of genetics at the molecular level. You will be able to explain how DNA is structured, how it is accurately copied, and how its instructions are precisely converted into functional molecules that determine traits and characteristics. What you'll learn: * Understand the chemical structure and physical properties of DNA and RNA. * Analyze the mechanisms of DNA replication, including the key enzymes involved. * Master the processes of transcription and translation that form the central dogma of molecular biology. * Apply knowledge of the genetic code to predict the amino acid sequence of a protein from an mRNA sequence. * Examine basic principles of gene regulation, including operon models and the role of non-coding RNA. We begin by defining key terminology and exploring the structure of nucleic acids. We then move step-by-step through the processes of DNA replication, transcription, and translation, concluding with an overview of how gene expression is controlled. This course is designed for absolute beginners in biology or anyone needing a foundational understanding of genetics. No prior knowledge of molecular biology is required.
