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
Restriktionsenzyme, oder Restriktionsendonukleasen, werden in vielen verschiedenen molekularbiologischen Anwendungen benutzt. Diese Enzyme erkennen und schneiden eine spezifische DNA Sequenz, die auch Erkennungssequenz genannt wird. Dieses Video behandelt wie diese unglaublichen Moleküle funktionieren und wie man einen Verdau ...
