[Diurnal periodicity of mitotic activity, DNA synthesis and duration of mitosis in mouse bone marrow cells].
A clear diurnal rythm of the mitotic activity and DNA synthesis was observed in the cells of myeloid and erythroid series of mouse bone marrow, maximum number of mitoses and DNA-synthesising cells coincided in time and occurred during day and night hours minimum--during morning and evening hours. A rise in the mititic activity was due to the increase in the number of dividing cells but not to the increase in duration of mitosis.
