A
4
2
Q

A
interphase
3
Q
what are the 4 stages of mitosis
A
prophase, metaphase, anaphase, telophase,
4
Q
prophase
A
chromosome condense
centrioles mo0ves to opposite end of cells
nuclear envelope break chromosome free in cytoplasm
5
Q
metaphase
A
chromosomes line up along the middle and they are attached to spindle buy their centromere
6
Q
anaphase
A
centromere divide.
sister chromatids are separated
due to spindle contracting, it pulls chromatids to opposite ends
7
Q
telophase
A
chromatids uncoil and become long and thin again
nuclear envelope forms
2 nuclei
cytoplasm divides forming new 2 daughter cells
8
Q
mitotic index
A
number of cells with visible chromosomes / number of cells observed
