title: [Changes in rat liver chromatin after administration of a mixture of amino acids].
abstract: It was shown that injections of an amino acid mixture essentially increase the number of nuclease-sensitive regions of chromatin and its active fraction (Mg2+-soluble fraction), while hydrocortisone increases the amount of the latter, which is less sensitive to the effect of DNAase II. Genome activation during nonhormonal induction after administration of the amino acid mixture or during hydrocortisone injection reflects in different ways on the parameters of melting of chromatin active fractions and on the relative content of its protein fractions.
