Apoptosis - Wikipedia
WEBApoptosis (from Ancient Greek: ἀπόπτωσις, romanized: apóptōsis, lit. 'falling off') is a form of programmed cell death that occurs in multicellular organisms and in some eukaryotic, single-celled microorganisms such as yeast. [1] Biochemical events lead to characteristic cell changes and death. [2]
