Microbiology Notes 2: Bacterial Reproduction Flashcards
(8 cards)
1
Q
DNA in bacteria
A
Double stranded not surrounded by a nucleus
2
Q
What are plasmids
A
Additional genetic info in bacteria
3
Q
What do plasmids do
A
Give bacteria advantages by making protein, help with:
Antibiotic resistance
Toxin production (help destroy immune cells)
Environmental survival
4
Q
How do bacteria reproduce
A
Binary fission
(Bacteria splits into 2 daughter cells, no nucleus, chromatic condensing, spindle formation)
5
Q
What are right conditions for bacteria growth
A
-pH
-Temperature
-Nutrients
6
Q
How do bacteria make genetic variation
A
- Mutations
- Transformation
- Conjugation
7
Q
What is mutations
A
Random and accidental changes in gene code
8
Q
What is conjugation
A
Genetic materials passed through another bacterium using pili
Makes drug restriction, toxin, survival proteins
