Please I would like to ask about guide RNA in CRISPR-Cas9 technique. Should we design guide RNA to match the whole invader gene and make double strand of DNA and RNA or just small pieces after PAM fragment is enough to bind the gene sequencing?
Please Amy as we know that the sequencing gene of COVID-19 is RNA, my question is could we use CRISPR-Cas9 in this virus, I meant we can design guide RNA to match the gene of COVID-19 or not?
