Which delivery method has been successfully used to administer CRISPR components inside living animals (in vivo) for therapeutic purposes?
- A. Viral vectors (AAV)
- B. Lipid nanoparticles
- C. Electroporation
- D. Gold nanoparticles
What is a major safety concern when editing genes in human embryos?
- A. Off‑target mutations that could affect unintended genes
- B. Increased lifespan of the edited individual
- C. Enhanced muscle growth in all tissues
- D. Improved vision in low light
What is the name of the first FDA‑approved CRISPR‑based therapy for sickle cell disease?
- A. Casgevy (exagamglogene autotemcel)
- B. Zolgensma
- C. Luxturna
- D. Kymriah
Which version of Cas9 creates a single‑strand nick instead of a double‑strand break, improving editing precision?
- A. Nickase Cas9 (Cas9n)
- B. Dead Cas9 (dCas9)
- C. Cas12a
- D. Cas13
In 2023, researchers used which tool to edit genes in crop plants to enhance drought resistance?
- A. CRISPR‑Cas9
- B. RNA interference (RNAi)
- C. TALENs
- D. Zinc finger nucleases
What does an "off‑target effect" mean in the context of gene editing?
- A. Unintended edits at DNA sequences similar to the intended target
- B. The desired edit occurring exactly at the target site
- C. A temporary increase in gene expression after editing
- D. Cell death caused by the delivery vehicle
