Abstract:
:We analyzed the connection of changes in nucleus ploidy with changes in nucleolar apparatus of NIH 3T3 cells. The quantity of nucleoli does not depend on the quantity of nucleolar DNA, but instead depends on euploidy: the majority of euploid cells have 1-3 nucleoli. The quantity of DNA in the nucleolus is correlated with the quantity of nucleolar DNA, and does not depend on ploidy changes. The nucleolar area has a tendency to increase in line with an increase in their numbers in the nucleus. The relationship of the quantity of DNA in the nucleolus with that of the nucleus is stable. During the process of increase in the number of nucleoli in a nucleus, there is a corresponding decrease in the quantity of DNA in each nucleolus, and there is likewise no increase in the sum of nucleolar DNA. The ratio of sums of the nucleolar perimeters to nuclear perimeter is a significant factor, which increases linearly along with an increase in the number of nucleoli in a nucleus.
