Basidiomycotes (club fungi):
-Basidiocarps fuse + and – to make spores
-Stores them in puffballs (basidiomycotes), then released when popped.
-+ and – hyphae fuse to make spores inside a sack (asci)
-Pressure builds up inside as spores mature and will burst, rapidly releasing pores shot out.
-Source of penicillin
-used to make blue cheese and soy sauce.
-By Definition, viruses are not living because they do not have cells
-Viruses made up of protein, and RNA/DNA Information
-They’re considerably smaller than most cells and bacteria
Classification by shape:
Icosohedral: 20 sided structure: Adenovirus
Mix of Helical and Rod:
Helical: orf virus
Classification by host/tissue:
Broad with any hosts: rabies
Limited range of hosts
Specific type of tissue: HIV only attacks white blood cells
Classification of RNA vs DNA
RNA: attach to cells and spit viral RNA into cell, they will attach and copy viral data onto the
cell until it bursts to let out more viruses
DNA: stick onto part of a DNA gene, hiding, destroying, or corrupting that gene, making it
unreadable. It could also insert itself between a genes, causing cancer. By reproduction type: through study of virus interaction with bacteriophages
1) Attachment: attaches itself on cell membrane
2) Entry: it injects part of the DNA inside the nucleic acid of existing cell
3) Replication: takes existing DNA material and copies viral information
4) Assembly: new virus particles are assembled
5) Lysis and Release: Host cell breaks open and releases viruses
Lysogenic Cycle: Infects host’s cells, injects viral DNA
-Viral DNA information live within the strands of normal chromosome
-As the normal cell replicates, it copies the viral DNA information with it also
-If the cell’s immune sequences have been compromised, the gene will leak out and make
the cell go through lytic cycle.
