The Genetics of Resistance to HIV Infection
|
|
This case uses the example of HIV, to explore
the relationships between viruses, cells and the immune
system, and the role of genes in disease resistance. An
animation explains PCR (polymerase chain reaction) and
electrophoresis and their practical use as a genetic test.
We will see how mutations in an HIV receptor confer relative
reslstance to infection. We will find out how often this
mutation occurs in the general population, and see data
about additional mechanisms of HIV resistance.
