Guide RNA (gRNA) or single guide RNA (sgRNA) is a short sequence of RNA that functions as a guide for the Cas9-endonuclease or other Cas-proteins [1] that cut the double-stranded DNA and thereby can be used for gene editing. [2]

2020年11月5日 · The team teased out some guidelines for guide RNA design, which led to their Rule Set 1 and Rule Set 2 — quantitative models to assess sgRNA on-target specificity.

This year’s Nobel prize for the CRISPR/Cas system is an illustrative example of how scientific breakthroughs rests on preceding work: the discovery of guide RNAs in the 1990s. Subject Categories: S&S: History & Philosophy of Science, RNA Biology.

Guide RNA refers to a RNA molecule that contains an anchor sequence and is used to direct the editing of preedited RNA by hybridizing with it and guiding the addition or deletion of nucleotides as directed by the template.

Engineered CRISPR systems contain two components: a guide RNA (gRNA or sgRNA) and a CRISPR-associated endonuclease (Cas enzyme). The gRNA is a short synthetic RNA composed of a scaffold sequence necessary for Cas-binding and a user-defined ∼20-nucleotide spacer that defines the genomic target to be modified.

2022年4月30日 · Guide RNA (gRNA): A specific RNA sequence that recognizes the region of interest in the target DNA. It binds with the Cas9 protein and directs it to the target site to perform the modification process.
