-Lytic cycle (11)
- The virus inserts its DNA into the host cell
- That DNA will move into the nucleus
- The machinery of the host nucleus replicates the viral DNA
- The viral DNA makes copies of itself called mRNA
- Each of the mRNAs go to a ribosome and influence the ribosome to create proteins that the virus needs
- The viral proteins assemble into new viruses and escape the cell; in the process the lyse the cell
- This happens in multiple cells at the same time; therefore viruses are propagated exponentially
- The genetic material is RNA; it travels along with the enzyme reverse transcriptase
- The virus injects RNA and reverse transcriptase into the host cell
- Reverse transcriptase takes the RNA and makes DNA out of it **the RNA has very high mutation rates (this makes the virus able to evade the immune system by constantly changing)
- The DNA moves into the nucleus then steps 3-7 of the lytic cycle follow (in this case, reverse transcriptase leaves the cell with the newly formed virus upon lysing it)

-Lysogenic cycle (11)
- The virus injects its DNA into a bacterium
- As the bacteria copy themselves, the viral DNA is also copied over and over
- From this point, the virus can eventually jump back to the lytic cycle
