Webcleavage: [noun] a fragment (as of a diamond) obtained by splitting. WebThe pattern of cleavage is not totally random but is localized in a way probably related to structural features of the DNA. The cleavage occurs in a two-step process: the DNA is first nicked in one strand and then, several seconds later, in the second strand at a site very close to the first one on the opposite strand.
