Migration of newly synthesized RNA during mitosis: I. Embryonic cells of the loach ( Misgurnus fossilis L.)

The behavior of newly synthesized nuclear DNA-like RNA during mitosis was studied by means of autoradiography in early loach ( Misgurnus fossilis) embryos at late blastula stage. It is demonstrated that in interphase cells labeled RNA is localized in the nucleus before onset of mitosis. With onset o...

Zusammenfassung:	The behavior of newly synthesized nuclear DNA-like RNA during mitosis was studied by means of autoradiography in early loach ( Misgurnus fossilis) embryos at late blastula stage. It is demonstrated that in interphase cells labeled RNA is localized in the nucleus before onset of mitosis. With onset of mitosis labeled RNA enters cytoplasm and after completion of the cell division returns to the nuclei of the daughter cells.
