A. When interphase nuclei are suspended in a solution of low ionic strength, they swell and rupture to release fibers of chromatin.

B. Individual nucleosomes can be obtained by treating chromatin with the endonuclease micrococcal nuclease

C. When chromatin is digested with MNase, the DNA is cleaved into integral multiples of a unit length can be Fractionated by gel electrophoresis reveals the “ladder”

D. With MNase more than 95% of nuclear DNA can be recovered in the form of the 200-bp ladder.
