Most common shape is icosahedral , some are helical shape
Protein capsid and genetic material some animal virus have
envelope with glycoprotein spikes
Onc: Oncogen is analogous to the Src gene - induce transformation
1. Epstein Bar Virus – Burkitt’s Lymphoma
2. Herpes Simplex type 2 – carcinoma of uterine cervix
3. Papilloma virus – uterine cervix
4. Hepatitis B – liver carcinoma
a. strain: organisms within the species varying in a given quality
b. types: organisms within the species varying immunologically.
2. Genus: closely related species
3. Family : closely related genera
Use nutritional patterns, as well as structure ones and biochemical properties, provide guidelines for classification of microorganisms. E.g.. Autotrophy, heterotopy, oxygen requirement etc.
(Plant like protist)
Branch protomycota (fungus like protists)
(animal like protists)
It is a procaryotes, different from bacteria.
Form lipid monolayer instead of lipid bilayer (in methanogens and thermophilic archaebacteria)
Archaebacteria has no muramic acid and D-amino acids.
Had pseudopeptidoglycan (use N-acetylglucosamine and N-acetyltalosaminuronic acid).
Most of them are thermphile or halophilic, or methanogens. Anaerobic.
(1) unicellular yeast
(2) muticellular molds
Budding processes (asexual reproduction) forming buds on the mother cell when mature, punch off to become new single yeast cells. sex spores (sexual reproduction), produce sex spores following the fusion of two separate cells.
Carry out a green plant type of photosynthesis resulting in the photolysis of water and the evolution of O2.
food storage is a lipoid polysaccharide - paramylum
food storage - starch
food storage – oil and leucosin (a polysaccharide)
have fucoxanthin, a brownish pigment
Mainly marine water algae
food storage – laminarin, a polysaccharide and mannitol, a sugar alcohol
food storage – starch, fat, oils
some elongated, some are oval.
