Heat Shock for Plasmid DNA Uptake

Description

Bacterial transformation lets cells take up foreign DNA from their surroundings. Some bacteria can do this naturally. In molecular biology, researchers recreate the process in the lab by making pores in the bacterial cell membrane.

Cells that can take up DNA from the environment are called compet...

Transcript

La transformation bactérienne est une méthode largement utilisée dans laquelle de l'ADN étranger est introduit à l'intérieur d'une bactérie, qui peut alors mutliplier, ou cloner l'ADN. Les cellules qui ont la capacité de prendre rapidement cet ADN sont appelées cellules compétentes. Bien que la transformation se produit nat...
