Front

What is horizontal gene transfer?

Back

The process by which an organism transfers genetic material to another organism without being the offspring of that organism.

Front

List the three common mechanisms of horizontal gene transfer.

Back

Transformation, Transduction, Conjugation.

Front

What is transformation in the context of horizontal gene transfer?

Back

The uptake of naked DNA from the environment by a bacterial cell.
