Prokaryote And Extra chromosomal 4

Question 1

Transposition

Answer 1

Can move genes between DNA molecules

Question 2

Conjugation

Answer 2

Can move DNA molecules between cells allowing opportunities for homologous recombination

Question 3

Transduction and transformation

Answer 3

Can move DNA molecules between cells allowing opportunities for homologous recombination

Question 4

What is the Mobilome ?

Answer 4

The mobile DNA sequences present in prokaryotes

Question 5

How to prokaryotes keep HGT under control ?

Answer 5

In Bacillus, Quorum sensing controls competence (ability to take up DNA) ensuring that transformation only occurs when population levels are optimal.
Prevents random, harmful gene uptake at low densities or under stress.
