Choosing the right tool for designing guide RNAs. The first step of CRISPR/Cas9 gene editing is designing a single guide RNA (sgRNA) to target your gene of interest. Because sgRNAs are solely responsible for recruiting Cas9 to specific genomic loci, optimal sgRNA design is critical for successful gene editing experiments.

The upgrade is deceptively simple: tag a “locking” structure to one end of the guide RNA so that only the targeted DNA can unleash the power of the Cas scissors. Yet exactly because the tweak is so easy, guide RNA 2.0 can fundamentally tune the accuracy of multiple CRISPR systems—not just those relying on the classic Cas9, but also newer

Before we get into the experimental details, let’s review how CRISPR works: CRISPR consists of a guide RNA (gRNA) and a DNA endonuclease, such as Cas9. The gRNA determines where gene knockouts will occur. These knockouts are also called insertions or deletions (indels). Once the gRNA and Cas9 are expressed in cells, the gRNA will direct Cas9

Guide RNA (gRNA) is a piece of RNAs that function as guides for RNA- or DNA-targeting enzymes, which they form complexes with. Very often these enzymes will delete, insert or otherwise alter the targeted RNA or DNA. They occur naturally, serving important functions, but can also be designed to be used for targeted editing, such as with CRISPR-Cas9

Choosing the right tool for designing guide RNAs The first step of CRISPR/Cas9 gene editing is designing a single guide RNA (sgRNA) to target your gene of interest. Because sgRNAs are solely responsible for recruiting Cas9 to specific genomic loci, optimal sgRNA design is critical for successful gene editing experiments.
Web-based sgRNA design tools typically require that users input a DNA sequence, genomic location, or gene name for each gene of interest, and indicate a species. An algorithm specific to each tool outputs a list of candidate guide sequences with corresponding predicted off-target sites for each input (Wu et al. 2014).
When using CRISPR people aim to make use of (2) or (3) but most of the time when people talk about CRISPR they usually just mean (3) but not always. The tracrRNA and crRNA, which when synthetically combined are called a “guide RNA” but also called sgRNA (synthetic guide RNA) or gRNA
