The video tutorial explores the nature of viruses, questioning if they are alive by examining their characteristics. It delves into the structure of viruses, including components like the capsid and nucleocapsid, and describes various virus types such as helical, polyhedral, enveloped, and complex viruses. The tutorial also covers the sizes of viruses and provides examples. Finally, it explains viral replication through the lytic and lysogenic cycles, detailing how viruses hijack host cells to reproduce.
