You design a guide RNA to target your gene of interest, which you will express attached to a scaffold RNA. You transform cells with Cas9, the guide+scaffold RNA, and an HDR template. The HDR template codes for the insertion of a premature stop codon located 10 bp upstream of the Cas9 cut site, a base pair substitution 15 bp upstream of the Cas9 cut site, and a base pair substitution in the PAM sequence. Question: Is this scenario “possible” or “not possible”? Cas9 cuts the target site, the stop codon and the two base pair substitutions are introduced.
