Lecture 5 - DNA Replication Flashcards
1
Q
Why do bacteria have toxin-antitoxin system?
A
It ensures that only cells with the plasmid after cell division will survive; selfish operon
2
Q
What happens if dont have plasmid with antitoxin/toxin?
A
then antitoxin CcdB bind to DNA gyrase preventing DNA replication because increase torsion from unrelieved positive supercoils.
