VIRUSES

THE CHARACTERISTIC :

•      Smaller size (25 – 300 micron)

•      Only shown by electron microscopes

•      Only can live in living things

•      acelluler (viruses is not a cel no cell membrane, no cytoplasm, and other organel)

•      Has only one nucleat acid (DNA/RNA)

•      Can be cristalized

•      Have various shape (oval, block, polyhedral and T-like shape)

THE STRUCTURE :

• a unit of viruses is called Virion contain Nukleat acid(DNA/RNA) and Protein kapsid consist of many sub unit is called kapsomer

CLASSIFICATION

• BASEN ON PLACE OF LIVE

1.      Bacteria viruses : if the viruses attach to bacteria, genetics material are DNA

2.Plant viruses  : if the viruses attach to plants, genetics material are RNA

3.Animal viruses : if the viruses attach to animals, genetics are DNA or RNA

§  BASED ON INDICATION DISEASE

1.      Virus causing common dissease as cacar, campak and demam berdarah

2.      Virus causing special disease, can only found in special organs as polio (syaraf),influenza(respiration),konjunctivic (radang pada mata), hepatitis (hati)

THE ROLE OF VIRUSE

The beneficial role of viruses

Cloning of gene and teraphy of gene, vaccination.

1. OPV Oral polio Vaccine) atau vaccin of polio

2. Vaccin of rabies

3. Vaccin of hepatitis

4. Vaccin of influenza

5. Vaccin of cacar

6. Vaccin of MMR (Measles, Mumps, Rubella) for cacar, gondong andcampak)

RNA VIRUSES

  1. Virus Toga (Demam Kuning)

  2. Virus Arena (Meningitis)

  3. Virus Picorna (Polio)

  4. Retro Virus (AIDS)

  6. Virus Hepatitis (Hepatitis C)

  7. Virus Orthomyxa (Influenza)

DIFFERENCE LITIC AND LISOGENIC

DIFFERENCE	LITIC CYCLE	LYSOGENIC CYCLE
CONTROL OF DNA	DNA of viruses	Combine DNA of viruses ana hospes (profage)
HOSPES	Lisis (the hospes is dead)	Not lisis
