Question

what practical applications have stemmed from research on the ubiquitin system?
improving satellite navigation
developing anti-cancer drugs
designing desalination plants
creating new vaccine schedules

Explanation:

The ubiquitin system regulates protein degradation in cells, which is critical for controlling cell growth and division. Dysregulation of this system is linked to cancer, so research on it has enabled the development of drugs that target this pathway to treat cancer. The other options are unrelated to cellular protein regulation research.

Answer:

B. Developing anti-cancer drugs
