Foundations of Virology: How Viruses Work and Replicate

Viruses occupy a unique and fascinating space on the edge of life, existing as acellular entities that rely entirely on host organisms to survive. To truly understand biology, medicine, and public health, one must first grasp how these microscopic entities function at a molecular level. This text-based course provides a clear, step-by-step introduction to the world of virology, taking you from basic concepts to a clear understanding of viral genomes and host-cell interactions. What you'll learn: - Understand the unique acellular nature of viruses and how they differ from cellular life. - Identify the structural components of virions, including capsids, envelopes, and genetic material. - Analyze the step-by-step process of viral replication and host cell hijacking. - Differentiate between DNA and RNA viruses and their respective evolutionary strategies. - Explore modern techniques used to study viral genomes and detect emerging viral threats. The course begins with essential terminology and foundational definitions before guiding you through the mechanisms of infection, host interaction, and contemporary scientific approaches to viral study. This course is designed for beginners, students of biology, or curious learners with no prior background in microbiology.
