Bacterial viruses call phage is a DNA molecule surrounded by a protein coat. The phage ejects itself in the cells. In the second experiment the p32 DNA carries the new generation of phage.

Aids is caused by HIV

Gp45 and others are attached into the membranes. HIV must attack the host cell, as well as the co-recptor.

A complementary strand joins non conveniently. Proviral DNA it remains dormant, rival RNA exits the membrane.

Treatment for HIV takes a lot of drugs. Particles can’t be produced when protease is inhibited. Chemical called Chemokine is what causes the cancer to attach to the CCR5, which is what causes the cancer.

Study of HIV, it shows that some peoples immune system fought the virus, and some allowed HIV to penetrate the cell.

For HIV to penetrate the cell it uses the outer protein to bind to two different cellular molecules. That is what joins to CCR5.

Some people exposed but not infected were missing a gene for the CCR5. The body made antibodies for the HIV. The guy was immune to HIV. This is very rare, even though he didn’t have CCR5 he still is alive, showing we can live without it.
