A student researching CRISPR has taken the following notes:
• CRISPR allows scientists to edit genes with unprecedented precision • The technology was adapted from bacterial immune systems • Potential applications include curing genetic diseases • Gene editing of human embryos raises significant ethical concerns • Clinical trials are underway for sickle cell disease and cancer treatments
The student wants to present both the promise and controversy of CRISPR. Which choice most effectively uses relevant information from the notes?
CRISPR technology was adapted from bacterial immune systems.
While CRISPR offers promise for curing genetic diseases through ongoing clinical trials, human embryo editing raises significant ethical concerns.
Clinical trials are currently underway using CRISPR for sickle cell disease and cancer treatments.
CRISPR allows scientists to edit genes with unprecedented precision.
Correct Answer: B
Choice B. Promise (clinical trials) and controversy (embryo ethics) presented together.
