What is a CRISPR Cas system?Bacteria and archaea have evolved various defense and regulatory mechanisms allowing them to react to various stressful situations caused by the environment, such as a virus attack. The recently discovered versatile CRISPR-Cas functions as a prokaryotic immuneKD Linse...
CRISPR System islike a type of immune system in these bacterial or prokaryotic cellsso it's a region on the bacterial genome 2. CRISPR locus This(the figure above) is called theCRISPRlocus(Clustered Regularily Interspaced Short Palindromic Repeats). What does that mean? The CRISPR locus is a...
CRISPR is a technology that can be used to edit genes and, as such, will likely change the world.
In harnessing this technology, researchers have added a new step: after DNA is cut by CRISPR-Cas9, a new DNA sequence carrying a “fixed” version of a gene can nestle into the new space. Alternatively, the cut can altogether “knock out” of a particular unwanted gene — for example, ...

What stops CRISPR from cutting up a whole genome? Applying CRISPR is of course not as simple as just running a piece of RNA along an entire genome: how can you control where the cuts take place? In bacteria, Cas9 enzymes are dependent on short DNA sequences called “PAMs” (short forpr...

Novel Applications of CRISPR/Cas9 Genome Editing Technology What is CRISPR? Oct. 16, 2017 When a virus infects a bacterium, it injects its viral DNA through the bacterial cell wall (1) and into the nucleus where it becomes integrated into the host's genome (2). From there, the viral...
