rapid degradation of somatic type histones is , however , observable upon incubation of elongated spermatid nuclei which have been treated with 5 mm hcl and are therefore free of acrosin or upon incubation of elongated spermatid chromatin where the majority of acrosin is removed , suggesting that the observed proteolysis of somatic type histones is not due to acrosin .
