Question 1.
What does CRISPR stand for?
Show hintHide hint
Think of it as an acronym for a bacterial defense mechanism.
Question 2.
What is the role of guide RNA (gRNA)?
Show hintHide hint
Remember, gRNA is like a map for the Cas enzyme.
3Question 3.
What does CRISPR stand for?
- Clustered Regularly Interspaced Short Palindromic Repeats
- Compactly Recorded Information about Specialized Pathogens
- Commonly Regulated Interventions in Selected Parts
Show hintHide hint
Think about the defense mechanism it provides to bacteria.
4Question 4.
True or False: Cas9 is responsible for making precise cuts in DNA.
- True
- False
Show hintHide hint
Remember the function of the Cas9 enzyme.
Question 5.
Consider a scenario where you need to edit a specific gene to fix a genetic disorder using CRISPR technology. Outline the steps you would take from the moment you choose your gRNA to the method of repair you would prefer to use, and justify your choices.
Show hintHide hint
Think about the importance of specificity in gene repair.
Question 6.
Analyze why NHEJ might be acceptable for certain applications while HDR is preferred for others. Discuss the implications in a research setting versus a therapeutic one.
Show hintHide hint
Consider safety and efficacy in the context of real-world applications.
