This video reviews the fundamental concepts surrounding viruses. It covers viral structure, the Lytic Cycle and Lysogenic Cycles of virus replication, types of vaccines, antiviral drugs and, of course the coronavirus SARS CoV-2.
Video Chapters
0:00-0:38 Introduction
0:38-1:28 What are viruses?
1:28-2:19 Virus Morphology
2:19-2:45 Viral Capsids
2:45-3:05 Viral Hosts
3:05-3:47 COVID-19
3:47-3:58 Viruses Hijacking Cells
3:58-4:22 Are Viruses Alive?
4:22-5:41 Lytic Cycle of Viral Replication
5:41-6:39 Lysogenic Cycle of Viral Replication
6:39-6:58 Preventing Infections
6:58-8:14 Types of Vaccines
8:14-9:18 Antiviral Medications (e.g. Tamiflu and NRTIs)
Virus structures include helical viruses, polyhedral viruses, spherical viruses (which includes coronaviruses) and complex viruses. Helical viruses include the tobacco mosaic virus. Polyhedral viruses include polio, hepatitis A, B & C, and adenoviruses. Spherical viruses include the novel coronavirus SARS-CoV-2, which causes COVID-19, in addition to influenza. Complex viruses include the T4 bacteriophage.
Replication can involve the lytic cycle either independently or in conjunction with the lysogenic cycle. In the lytic cycle, a virus attaches to a host, replicates, then the cell bursts and releases still more viruses. The lysogenic cycle includes adding a piece of bacterial genetic material into the host cell's genome.
This video also reviews the principles behind vaccines and antiviral medications, such as Tamiflu.
