Question
the centromeres divide; the sister chromatids separatei and a set of chromsosomes moves toward cach pole the spindle poles, where sew euclear envelopes develop During telophase, the chromosomes have clustered together neair around them The spindle begins to disappear as the daughter muclei form Summary the nuclei in the Somarize mitosis The nucleus in the mother cell has the diploid (2N) mumber of chromosomes, and daughter celils also have the number of chromosomes. Mitosis is cell division in which the chromosome Mitosis Models (the total Idemy the stages in the models using igure 4.4 as a guide. What is the diploid (2N) umber of chromosomes t number observed) in cach nucleus of the cells?

The nucleus in the mother cell has 2N number of chromosomes and the nuclei in the daughter cell also has 2N number of chromosomes.
Mitosis is the type of cell division in which the number of chromosomes remains same .
The each daughter cell has same number of chromosome as in the parent cell in mitosis while the number of chromosomes becomes half of that of parent cell in meiosis.
In figure 4.4 the number of chromosomes 2N is 12. Or N= 6 chromosomes.
2N means the organism is diploid having one set chromosomes from father and one from mother.
For example in humans 2N = 46 ,means we have 23 pairs or 46 chromosomes, 23 from father and 23 from mother. Here 2N is 46 while our gamates i.e. sperm or ova has N number of chomosomes i.e 23.
