The HIV viral cycle. Step 1: the HIV fuses to the host-cell surface. Specifically, the gp120 proteins on the surface of the virus binds to the CD4. This then binds to a smaller coreceptor (CCR5 or CXCR4). Step 2: HIV RNA, reverse transtriptase, integrase, and other viral proteins enter the host cell. The virus is brought into the host cell and uncoated; both viral RNA and reverse transcriptase are loosed into the cell. Step 3: Viral DNA is formed by reverse transcription. Step 4: Viral DNA is transported across the nucleus and integrates into the host DNA. Integrase found on the viral DNA. The viral DNA in the host DNA is called provirus. Step 5: New viral RNA is used as genomic RNA and to make viral proteins. New viral RNA strands are made and leave the nucleus. Step 6: New viral RNA and proteins move to the cell surface and a new immature HIV forms. The viral is assembled in an outbulging of the host cell. Step 7: The virus matures when protease releases the proteins that form the mature HIV. Mature virion is released.

The steps of specialized transduction. Step 1 is viral attachment and penetration. This is when the phage infects a cell. This shows the virus sitting on the outside of a cell and injecting DNA into the cell. Step 2 is integration when the phage DNA becomes incorporated into the host genome. Step 3 is excisionwhen the phage is excised from the bacterial chromosomes along with a short piece of bacterial DNA. The DNA is then packaged into newly formed capsids. When the virus particles are assembled the DNA contains both viral and host segments. Step 4 is infection when the phage contains both viral and bacterial DNA infects a new host cell. Step 5 is recombination when the phage DNA along with the attached bacterial DNA are incorporated into a new cell. The image shows a new bacterial cell with virus DNA as well as other bacterial DNA in its genome.
