CRISPR: Genome Editing Basics
In this video, I introduce genome editing and focus on how the CRISPR-Cas system can be used to precisely cut a genome in the correct location. Relevant links: A single guide RNA can be formed with a linker connecting the crRNA and the tracrRNA: http://www.sciencemag.org/content/337... (Charpentier/Doudna labs) Proof of concept: Genome editing in human cells: … Continue reading CRISPR: Genome Editing Basics
CRISPR: Acquired Bacterial Immune Systems
This is the first episode about the CRISPR system in bacteria, but it won't be the last. Here, I discuss an important paper that proved the acquisition of bacteriophage sequence and integration of that sequence into a CRISPR locus provides bacteria with resistance to the bacteriophage. 2007 (not 2006) paper in Science by Barrangou et … Continue reading CRISPR: Acquired Bacterial Immune Systems
