Viral Diseases
These animations from the Wellcome Trust, illustrate that, unable to replicate without using the cellular machinery of more complex organisms, viruses invade and hijack their host's cells, resulting in serious disease.
The animations use the examples of Dengue virus to show how an RNA virus replicates using the ribosomes in a host cell's cytoplasm. HIV is used as an example of a retroviruus which produces DNA that is integrated into the host cell's genome.
The animations contain a lot of detail and can be used with students aged 16+.

Dengue Virus Replication and Transmission
Produced by the Wellcome Trust, these animations take a detailed look at the molecular mechanisms that allow the dengue virus to subvert the cells of its mammalian host, allowing it to replicate and spread. Dengue is an example of an RNA virus.
...HIV Life Cycle
This animation, from the Wellcome Trust, shows how the human immunodeficiency virus (HIV) infects white blood cells and uses its RNA to produce a strand of DNA which becomes integrated in the host cell's genome.
