You are excited to try your first CRISPR experiment. You introduce Cas9 and one sgRNA into a dish of cultured human cells. You then sequence DNA from four different cells and obtain the results of sequences 1-4 below. You decide to repeat your first CRISPR experiment using Cas9 and two different sgRNAs into a dish of cultured human cells. You sequence DNA from three additional cells and obtain the results of sequences 5-7. Which type of endogenous DNA repair would produce the results in all seven of these cells following a Cas9 double-strand break
