網頁2024年9月1日 · When the target DNA is found, Cas9 – one of the enzymes produced by the CRISPR system – binds to the DNA and cuts it, shutting the targeted gene off. Using modified versions of Cas9, researchers can activate gene expression instead of cutting the DNA. These techniques allow researchers to study the gene’s function. 網頁2024年3月29日 · This alteration in secondary structure could impede either gRNA seed interactions with the target DNA or scaffold interactions with the Cas9 protein, resulting in a decrease in efficiency. Since the scaffold sequence in positions 52–53 is AA, T nucleotides at the 3′ end of the gRNA could lead to additional base-pairing, resulting in decreased …
