1 of 27
What do all viruses have structurally?
Protein capsid & nucleic acid genome
2 of 27
What is this describing?
Widespread in the environment
In many hosts (humans)
Useful for biotechnology
Single Cellular
Prokaryotic
Bacteria
3 of 27
What is this describing?
Extreme prokaryotes; live in thermal vents and saline environments
Creates biogas and methane
Single cellular
Prokaryotic
Archaea
4 of 27
What is this describing?
Require a host and cannot sustain themselves
No cellular organisms, just genetic material
Involved in pathogenicity, infection treatment and biotechnology.
Some have enzymes and lipid envelope
Rod or spherical shape
Viruses
5 of 27
What microorganisms carry out these roles?
Pathogenicity, infection treatment and biotechnology
Viruses
6 of 27
What is being described?
Virus that infects bacteria
As varied as eukaryotic viruses
Only the genome is injected in
Two routes: Rapid proliferation and creation of prophages
Could help with antimicrobial resistance
Bacteriophage
7 of 27
Lytic viral life cycle, fill in the gaps
1. The (1) attaches
2. Injects its (2) into the cell
3. (2) replicated by host systems
4. New (1) are formed
5. Phage grow until cell (3), aka (4), releasing phages into environment
1. Bacteriophage 2. genome 3. bursts 4. cell lysis
8 of 27
Lysogenic viral life cycle, fill in the blanks
1. (1) attaches and injects (2) into cell
2. The phage (3) integrates into the chromosome of the host
3. External stimuli causes an excision of the phage. This isn't precise so some host (3) is attached to th
1. Bacteriophage 2. genome 3. DNA
9 of 27
What is being described?
Case studies: Ebola Corona & Zika
Materials known or expected to contain a pathogen
In RNA viruses, fast mutation rates
Aetiological agents
10 of 27
What is being described?
Can thrive in every habitat on Earth
So diverse they encompass two domains of life
Single celled
Contain a single circular chromosome
Are encapsulated in a cell membrane and a cell wall
Reproduce using binary fission
Prokaryotes
11 of 27
What was the
a. primary electron donor
b. primary terminal electron acceptor
in the beginning of earth
a. hydrogen b. sulfur
12 of 27
What are these an example of?
Hyperthermophiles
Halophiles
Methane
Archaea
13 of 27
What are the 3 basic methanogen metabolisms?
Hydrogenotrophic, methylotrophic, acetotrophic
14 of 27
What is this describing?
Multicellular
Nucleated off-spring of a union between Archaea and Bacteria
Eukaryotes
15 of 27
What is cryobiosis?
low temperatures
16 of 27

lack of oxygen
19 of 27
What are extremotolerant animals important for?
Soil turnover, pathogen suppression, experimental organisms
20 of 27
What is being described?
Multicellular
Microscopic animal
Asexual
High level cryptic speciation
Global distribution of diversity
Generate genetic diversity when desiccated and hydrated again.
