Aaron Ciechanover's research primarily involved which molecular component?

  • RNA

  • DNA

  • Ubiquitin

  • Insulin

Answer

Ubiquitin is a small, regulatory protein that tags other proteins for degradation by the proteasome. Aaron Ciechanover's research primarily involved the role of ubiquitin in the regulation of protein degradation. He discovered that ubiquitin is covalently attached to proteins by a series of enzymatic reactions. This attachment marks the proteins for degradation by the proteasome.
