DNA is the genetic code (chromosome molecule) of all living organisms that allow it to replicate and grow. DNA is composed of genetic and heredity codes. Under the microscope it looks like a double-strand helix pattern – where two (2) RNA (single strand) molecules wrap around each other. HIV is a single strand RNA virus that ‘steals’ another single strand from the human host cell DNA, to form its own DNA so it can produce more virus particles which continue to infect other cells in the body. HIV antiretroviral treatment blocks this process of HIV assembly against invading the body’s human host cell DNA.
