- Retroviruses
- This site from the University of Leiceister's Department of Microbiology and Immunology has detailed information about retroviruses. There is also a link to the Microbiology Video Library where you can download Quicktime video clips of HIV replication and maturation.
- The Body
- An AIDS and HIV information resource with lots of information about the disease. HIV is a retrovirus.

DNA and proteins are key molecules of the cell nucleus.
One gene makes one protein.
A gene is made of DNA.
Bacteria and viruses have DNA too.
The DNA molecule is shaped like a twisted ladder.
A half DNA ladder is a template for copying the whole.
RNA is an intermediary between DNA and protein.
DNA words are three letters long.
A gene is a discrete sequence of DNA nucleotides.
The RNA message is sometimes edited.
Some viruses store genetic information in RNA.
RNA was the first genetic molecule.
Mutations are changes in genetic information.
Some types of mutations are automatically repaired.
