Study Notes

Extra Chromosomal Genetic Elements

Extra chromosomal elements are not essential for bacterial survival
They can transfer genetic material between cells
Plasmids and transposons are examples

Plasmids

Circular DNA molecules
Located outside the bacterial chromosome
Can replicate independently
Carry genes for:
- Antibiotic resistance
- Bacteriocins production
- Enterotoxin production
Can be transferred between bacteria via conjugation

Transposons

Small DNA segments
Can move within and between DNA molecules
Not capable of autonomous replication
Are considered "jumping genes"
Encode the enzymes needed for their movement
Exist in extrachromosomal form
