Which biological process did Aaron Ciechanover characterize?
Photosynthesis
Protein synthesis
Cell degradation using ubiquitin
Cell division
Answer
Aaron Ciechanover won the 2004 Nobel Prize in Chemistry for characterizing cell degradation using ubiquitin. Ubiquitin is a protein that tags other proteins for destruction. Ciechanover showed that ubiquitin is added to proteins by a series of enzymes, and that this tagging process is necessary for the proteins to be degraded by the proteasome.
