<prompt> Ladder pattern of DNA electrophoresis in apoptosis is caused by the action of the following enzymeEndonucleaseTransglutaminaseDNAseCaspase  <response>: 1.Apoptosis progresses quickly and its products are quickly removed, making it difficult or visualize. 2.During karyorrhexis endonuclease activation leaves sho DNA fragments, regularly spaced in size. 3.this gives a characteristic laddered appearance on agar gel electrophoresis. 4.This laddered pattern is characteristic but not specific for apoptosis..It may seen in necrosis also.
