Question: Which of the following statements regarding CRISPR/Cas9-mediated gene editing is true? Group of answer choices The PAM sites used in generating a deletion will be retained following gene editing. All CRISPR/Cas9-mediated gene editing depends on knowledge of the primary structure of the genome. An organism that does not encode a Cas protein cannot have its genome edited by CRISPR/Cas9. Multiple sgRNAs are necessary for generating a deletion by CRISPR/Cas9. None of the above.
