[Activity of embryonic mink genome during diapause (cytogenetic analysis): nucleolar and extranucleolar rna synthesis]. / Activnost' c'mbrional'nogo genoma norki vo vremia diapauzy (tsitogeneticheslii analiz): iadryshkovoi i vneiadryshkovoi sintez rnk.

ABSTRACT

The nucleolar and extranucleolar RNA synthesis was studied in the mink blastocysts at different stages of embryonic diapause and during the periimplantation period using cytoradioautography. The data obtained suggest a differential and stage specific activity of the embryonic mRNA and rRNA synthesis during the period of delayed implantation.
