Answer »Answer: (c)
Aaron Ciechanover, Avram Hershko and Irwin Rose have been awarded the Nobel Prize in Chemistry in 2004 for “...helping to understand how the human body gives the ‘kiss of death’ to rogue proteins to defend itself from diseases like cancer” (Reuters, 6 October 2004).
These scientists—the former two from Israel, the latter from the US — discovered ubiquitin-mediated protein degradation.
Knowledge of ubiquitin-mediated protein degradation offers an opportunity to develop drugs against cervical cancer, cystic fibrosis and other diseases.
