Restriction Enzymes: DNA Cutting Guide
Description
Restriction enzymes are bacterial proteins that cut DNA at specific sequences. They are also called endonucleases. In bacteria, these enzymes help defend against bacteriophages, which are viruses that infect bacteria. The bacterial DNA is protected because methyl groups are added, so the restriction enzymes cut the invading ...

Transcript
Les enzymes de restriction, ou endonucléases de restriction, sont utilisées dans une variété d’applications en biologie moléculaire. Ces enzymes reconnaissent et adhèrent à une séquence spécifique d'ADN, appelée site de restriction. La vidéo que vous allez regarder fournit quelques informations contextuelles sur ces molécules...
