1
Q
What is a nucleoid?
A
Region of cytoplasm where prokaryote’s genome (DNA) is located.
Usually contains a singular, circular chromosome.
2
Q
What is a plasmid?
A
Small extra piece of chromosome/genetic material.
Contains 5-100 genes and is not critical to everyday functions.
3
Q
What can plasmids provide genetic information for?
A
- Antibiotic resistance
- Virulence factors
- Promote conjugation
Conjugation is the transfer of genetic material between bacteria through cell-to-cell contact.
4

False
Nucleoids are characteristic of prokaryotic cells.
5
Q
