Facts
Viruses are living
What is NO?
Two types of virus types
What is Naked and Enveloped viruses?
Latin for Virus
Poison
What are bacteria? (2)
Single celled organisms
Very small
Can be found on most materials and surfaces
Bacteria are non-living organisms
What is FALSE?
Direct contact with bacteria will occur when touching a pen used by an infected person. (T/F)
What are the three basic shapes of bacteria?
- bacilli
- cocci
- spiral shaped
Lytic
What is break open / explode / destroy?
differences between bacterial and human cells
bacteria have:
- no nucleus
- PROKARYOTIC (no membrane bound organelles)
- No intracellular organelles
In the lysogenic replication cycle, the lysogenic cycle occurs after the lytic cycle.
False
Lysogenic cycle occurs first and then will turn to the lytic cycle once the cell is under stress.
All bacteria are bad and cause harm to the body (pathogens).
No, some are helpful; create cheese, help us digest food, produce vitamins, used to produce yogurt, buttermilk, and other products.
Part of cell where proteins are made
What are ribosomes?
What is Viral Specificity?
What is gene therapy?
Inserted desired DNA into a cell using a non-harmful virus.
Bacteria grow in size
FALSE
Grow in number and not size
4 Stages of Lytic Cycle
What is:
1) Attachment & Entry
2) Replication
3) Production and Assembly
4) Lysis and Release
3 Things that viruses contain:
1) Nucleic acid or RNA/DNA
2) Protective protein capsule
3) Docking proteins
Bacilli
rod shaped
Four methods of bacteria getting food
- scavengers
- warriors
- decompose
- mutualistic
Viruses can be general or specific.
Give examples.
What is true?
General - influenza
Specific - HIV
All strands of E. coli are bad for you (T/F)
No,
one type helps you digest food.
Difference between capsule and cell wall
Capsule - keeps the cell from drying out and helps it stick to things
Cell wall- thick outer covering that keeps the shape of the bacterial cell
Cocci
Round shaped
How do bacteria make you sick?
- they produce toxins that result in fever, headache, vomiting, diarrhea, and destroy body tissue
- they reproduce and increase in number
Pilli is the part of the bacterial cell that is used to move around.
False
Flagella move the cell around
Pilli allows bacteria to attach to other cells.
