Practice questions testing deep understanding of CRISPR-Cas9 mechanics and ethical implications.
Q1. The CRISPR-Cas9 system was not invented by humans; it was discovered in bacteria. What is the original, natural biological function of the CRISPR-Cas9 system in a bacterial cell?
Q2. A scientist wants to use CRISPR to cure a genetic muscle disease. They have two options: somatic cell editing (editing the muscle cells of an adult patient) or germline editing (editing an embryo). Explain the critical ethical and biological difference in the long-term outcome of these two approaches.
Q3. Assertion (A): The Cas9 protein relies entirely on a guide RNA (gRNA) to function. Reason (R): Cas9 is just a pair of "molecular scissors" that can cut DNA anywhere; it is entirely "blind" without the gRNA, which chemically matches the target DNA sequence and physically leads the Cas9 to the correct cutting site.
