Today you will go over the Introduction to Microbiology Notes, which cover Virus, and Monerans, with a mention of unicellular fungi.
STEPS TO THE LYTIC CYLE: memorize AESAR
- Attachment
- Entry & degradation of host's DNA
- Synthesis of new viruses
- duplication of virus' genetic material
- creation of new virus parts
- Assembly of parts into new viruses
- Release of new viruses

steps to the lysogenic cycle: memorize AEIM
- Attachment
- Entry (no degradation of host DNA)
- Integration using integrase enzyme
- Mitosis
- Host+virus DNA duplicated
- cytokinesis
- A virus that uses the lysogenic life cycle is termed either a provirus or prophage. What causes various proviruses to shift to the lytic cycle is not completely understood, but in some cases stress is the stimulus.
