3.24a Mitosis


mitosis=
cell division resulting in growth/ increase in number of cells

beginning with a normal cell with its nucleus 
--> number of chromosomes in the nucleus its called "diploid number" (2n)
humans 2n=46
cats 2n=38

- inside the nucleus each cell have a diploid nucleus which are identical (daughter cell) 
- same # of chromosomes 
- same set of chromosomes
whatever you found in one of the nucleus you will find the same chromosome in the other nucleus

How are the copies made and how will they be separated?
