The Cas9 nuclease and requirements for RNA-guided genome-editing. Cas9 is the nuclease guided by the crRNA and tracrRNA (or trans-activating crRNA) to cleave specific DNA sequences (Deltcheva et al.2011). A guide RNA (gRNA) can be designed to include a hairpin that mimics the tracrRNA-crRNA complex (Jinek et al. 2012).he Cas9 nuclease and requirements for RNA-guided genome-editing.

Solid Surface Bathroom Countertops: These countertops are made from synthetic materials, so they are manufactured in many colors and styles. The pros of solid surface countertops include the choices, strength and a non-porous surface that cleans up quickly.
Quartz countertops are an engineered stone product used in residential and commercial kitchen and bath applications. Quartz countertops are made by mixing and compressing natural quartz derived from granite and epoxy resins to create a hard wearing and stain-impervious surface.
