The Lifecycle of a Virus

The video tutorial explains the nature of viruses, highlighting that they are not true organisms as they cannot replicate independently. It describes the basic structure of viruses, including genetic material and a protein coat called a capsid. The tutorial covers how viruses replicate by infecting host cells, detailing the lytic and lysogenic cycles. In the lytic cycle, viruses inject genetic material into a host cell, leading to the production of new viruses and cell lysis. The lysogenic cycle involves the integration of viral genetic material into the host's chromosome, allowing replication with the host cell. The video concludes with a summary of these cycles.
