9

What is required for Transformation? What are the steps?

A competent cell

1. Bind DNA
2. DNA uptake
3. DNA integration

10

What is transduction?

Transfer of DNA using a virus (bacteriophage)

11

Recombination follows which events of DNA exchange?

Transformation
Transduction
Conjugation

12

Which RNA virus shows legitimate recombination?

Picornaviridae

13

What is a lytic infection?

Terminal, destructive, common type of infection where infection takes place and more virus is produced, cell undergoes lysis and virus spreads.
