How microscopic invaders hijack cells to trigger disease
In short: Explore the fundamental mechanics of viruses, from their tiny structures to the way they replicate by damaging host cells and causing widespread illness.
This video examines the biological characteristics of viruses, including their size, structure, and replication processes. It details how these pathogens compromise host cells to induce disease.
The lesson covers three specific examples: the transmission and vaccination of measles; the progression of HIV to AIDS and the role of antiretroviral drugs; and how Tobacco Mosaic Virus (TMV) disrupts photosynthesis and growth in plants by creating mosaic patterns.
