Title: CRISPR-Cas9
Post by: Avni on February 16, 2024, 12:05:52 AM
I am doing a project and my partner and I are just not understanding the terms: "Non-homologous end joining pathways" and "Homologous direct repair mechanism."

What is the difference between a sgRNA and an sgRNA-Cas9 complex?

I'm a little confused on PAMs. Is a PAM something that is in the DNA that is necessary for CRISPR-Cas9 to be done, or is it something that CRISPR always edits? Is it something like the sgRNA, that helps guide the CRISPR and the CRISPR will ALWAYS cut 3-4 nucleotides away from it? Does PAM repeat every now and then?

The answer to this question varies when I look at different sources, some say that gRNA is a combination of tracrRNA and crRNA and some say that gRNA is a general term for all locator RNAs...
