Q

List Lytic cycle in order

A

Attach to host cells, Bind to receptors, Injects nucleic material, Virus directs host to use its resources to reproduce cell parts, when directed/activated they assemble, lyse and escape the host

Q

List Lysogenic cycle in order

A

Attach to host cells, Bind to receptors, Injects nucleic material, material binds and hides in host’s genetic material, as cell reproduces virus material is too, when directed/activated they assemble, lyse and escape the many hosts.

25
How are virus's treated
NOT treated with antibiotics but is symptoms based
26
How are virus's prevented
hand washing, proper sanitation, vaccines
27
what are viroids
effects only plants, viruses, potato tuber spindle disease, RNA
28
What are Prions
effects animals, protein (not DNA/RNA), from sobemoviruses family
29
Prion defintion
an infectious particle
30
Virion definition
a long strand of RNA that self-reproduces
31
Two Kingdoms of Bacteria
Archaebacteria and Eubacteria
32
What are Archaebacteria
Live is harsh environment, cell wall has no peptidoglycan, bacteria
33
Four examples of Eubacteria
Gram + Gram - (often make sick) E coli (type of gram -) Cyanobacteria
34
what is a Eubacteria
Everywhere, ubiquitous, cell wall has peptidoglycan
35
Four examples of Archaebacteria
Chemosynthesizer (seas bottom) Extreme Halophile (Super salty) Methanogen (make methane) Thermoacidophiles (acid/ heat)
36
List three shapes of bacteria
Bacillus (Rod) Coccus (Sphere) Spirilla (spiral)
37
How do bacteria move
flagella
38
two examples of Coccus bacteria
MRSA, sore throat (strept)
39
two examples of Spiralis bacteria
poliphilus, Stomach ulcers, Syphilis
40
Heterotroph definition
Consume carbohydrates
41
Autotroph definition
Make carbohydrates
42
Heterotroph examples
Animals, Photoheterotrophs, Chemoheterotrophs
43
Photoheterotroph definition
needs sunlight for energy but must consume things for carbon
44
Chemoheterotroph
need consumption for all functions (people)
45
Examples of Autotrophs
plants, Chemoautotrophs, Photoautotroph
46
Chemoautotroph
Chemicals used for energy and carbon
47
Photoautotroph
Sun used for all functions
48
Obligate aerobe bacteria
Need oxygen to live
49
Obligate anaerobe bacteria
Can not be around oxygen
50
Facultative anaerobic bacteria
Can live with or without oxygen
51
How do bacteria reproduce
Binary fision
52
Generation time definition
Time for bacteria to reproduce or double population
53
generation time for E coli
20 minutes
54
Steps of Binary fission
Cell elongates, Nucleic Acid is duplicated, Cell wall starts growing in, cell wall and membrane gro all the way through cell, cell splits
55
What is conjugation
genetic material is shared through genes between organisms
56
how does conjugation result in increased genetic diversity
Genes are shared
57
What environmental conditions lead to formation of endospores
Nutrient depletion, environmental stress
58
What are endospores
a "sac-like" thing that allows bacteria to remain dormant until correct conditions
59
Are these bacteria or virus: cold, tooth decay, strep throat, influenza (flu)
Cold- virus Tooth decay- bacteria strep throat- bacteria influenza- virus
60
Are bacteria prokaryote for eukaryote
Prokayotic
61
Antibiotics only work on...
Bacteria
62
What are three helpful functions of bacteria
fixing nitrogen, making food (yogurt/ cheese), make vitamins (K)
63
What is Koch's postulate
1) the bacteria must be present in every case of the disease and must not be present in a healthy organism 2) the bacteria need to be extracted from the host and grown in pure culture and identified 3) the bacteria are inoculated back into a healthy host and must then cause the onset of the disease 4) the bacteria must be extracted from the inoculated host and grown in pure culture to be identified as the original causative agent.
64
What is germ theorem
infectious disease caused by microorganisms too small to see without a microscope
65
What is the miasma theory
Old outdated theory saying that disease was caused by bad smells
66
How has Koch impacted what we know today
Laid foundation for medical treatments and discoveries were made
67
Pasteur's experiments effected disease knowledge
Better sanitation practices because he says microorganisms cause disease
68
Three methods to transmit disease
Contact, Droplet, Airborne
