Topic 3: The structure of viruses

A. VIDEOS 

1. Structure of Viruses
2. Viral symmetry
3. Viral structure and functions
4. Capsid structure and symmetries of viruses

B. LEARNING OUTCOMES

By the end of the lesson, students should be able to:

1. Define viral structure and identify the main structural components of viruses.

2. Describe the composition and function of viral nucleic acids, distinguishing between DNA and RNA genomes.

3. Explain the structure and role of the capsid, including capsomeres and symmetry.

4. Differentiate between helical, icosahedral, and complex viral symmetry.

5. Describe the structure and function of the viral envelope, including glycoprotein spikes.

6. Differentiate between enveloped and non-enveloped viruses based on structural features.

7. Explain the role of viral proteins and enzymes in attachment, entry, and replication.

8. Illustrate and label the basic structure of a virus using diagrams or models.

9. Relate viral structural features to stability, transmission, and infectivity.

10. Apply knowledge of viral structure to laboratory identification, diagnosis, and disease control.
