Prokaryote & extra-chromosomal genetics 1
Flashcards do conjunto (14)
- 1Most prokaryotes have haploid or diploid cells?Haploid
- 2What is their cell cycle called?Binary fission
- 3Prokaryotes non-meiotic processes for shuffling genes:1)Conjugation
2)Transduction
3)Transformation - 4Plasmid contains ori sequence what does it do?oriP recruits host cell enzymes to replicate plasmid DNA
- 5R plasmids?Carry genes that make it resistant to multiple antibiotics
- 6Example of this?R plasmid pG01 found in Staphylococcus strains from hospital infections
- 7How are plasmid genes transferred from chromosome to plasmids?Transposable elements
- 8What are they?Mobile DNA sequences, jump from one location within DNA molecule to another
- 9Insertion sequences (IS)=Simplest transposable elements
- 10Example of conjugation plasmid=E.Coli F plasmid
- 11What produces Pilus on prokaryotes?Tra - genes on plasmid
- 12Conjugation=•Plasmid containing cell
•Grabs hold of another cell not containing plasmid
•Infects it with copy of plasmid
=2 cells with same plasmid - 13Why is pG01 dangerous?Can transfer antibiotic resistance between populations of Staphylococcus cells
- 14Transposase enzyme=Can take chunk of DNA with it
