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.
A Typical Receptacle Mounting Height. A typical bathroom counter is 32 to 36 inches above the floor. A bathroom counter usually has a 4-inch backsplash, where the counter surface turns up the wall. Backsplashes prevent water from running behind a countertop. An electrical outlet receptacle is usually placed 2 to 3 inches above the top of the backsplash. The outlets can be placed horizontally or vertically.
