Distribution of the NORs between the emerging daughter HeLa cells in telophase

	0	1	2	3	4	ED	NED
Model	0.22	0.34	0.28	0.14	0.02	1.40
Experiment	0.64	0.32	0.03	0.01	0	0.41	0.03

The table shows frequencies with which the number of rDNA FISH signals in the daughter cells differs by 0 (symmetrical distribution), 1, 2, and so on. The data, obtained from 200 cells, were compared with a random pairing model (see Section 2.3). In most cases NORs, in contrast to the competent NORs, were equally distributed between the daughter cells. The value of ED shows that in average daughter cells differed by less than one signal. Low value of NED emphasize the contrast with the case of competent NORs (Compare Tables 1 and 2).
