True or False: CRISPR-Cas9 can be used for both gene editing and gene regulation without cutting DNA.
- True
- False
Answer: True
Dead Cas9 (dCas9) fused with activators/repressors can regulate gene expression without DNA cleavage (CRISPRa/i). Standard Cas9 cuts DNA for editing. This versatility expands therapeutic applications. [[DBT Reports, NCERT Biology Class 12]]
