Study Notes
Virus:
- A virus is an infective and disease producing agent made up of nucleic acid enclosed in a protein covering.
- Viruses can only reproduce by entering a living cell.
- The human body combats viruses by producing an antiviral protein, interferon.
- Retroviruses have an RNA genome and can produce DNA from this RNA.
- Drugs to fight viruses are difficult to develop.
- Some viruses gradually develop resistance to antiviral drugs.
- Viruses damage the organism by producing other viruses. Bacteria:
- Bacteria are unicellular organisms that can have various forms and sizes.
- Bacteria consist of a circular DNA molecule surrounded by cytoplasm, plasmatic membrane, and a cell wall.
- Bacteria can reproduce in two different ways: simple binary division and gemmation.
- Bacteria can be dangerous/harmful/lethal or helpful/useful/harmless.
