PRECISION EDITING USING CRISPR - GENE EDITING EXPLAINED!

This series of short presentations on gene editing is brought to you by Dr Adam West, College of Medical Veterinary and Life Sciences at the University of Glasgow, Scotland. https://www.gla.ac.uk/people/adamwest This presentation describes the use of the following three strategies for precise genome editing with CRISPR: 4:13 Homology-directed repair 8:32 Enzymatic base editing 11:34 Prime editing using reverse transcription This is part of a series (   • Genome Editing Explained  ) that also covers Zinc finger nucleases (ZFNs) TALE nucleases (TALENs) CRISPR adaptive immune systems Using CRISPR/Cas9 for genome editing CRISPR specificity This presentation is primarily aimed at university students, researchers, clinicians and journalists interested in fields related to molecular biology and genetics. It is for education purposes only. Please leave a comment to let us know whether this was helpful to you and what you think we should cover next. We are a new channel so please give us a like and share our video on your social media if you think others should see it. We have a lot of content coming up, so please subscribe! More accessible presentations for a wide audience can be found in the “Explained Simply” section of this channel in the near future.
