The cell forms a tight compass and its tissue layer undulates, resulting in bulges called blebs. The nuclear membrane breaks, and endonucleases clip chromosomes where the desoxyribonucleic acid peeks out from protective proteins. This occurs at 180-base intervals, so the DNA pieces are all the same size. Then the cell fragments, with enough membrane sequestering toxic cell contents to prevent inflammation at the site. Finally, nearby cells consume the remains. (In contrast to this...If you want to get a full essay, order it on our website: Ordercustompaper.com
