The first and longest phase of mitosis, chromosomes become visable

Prior to cell division each chromosome is copied, each chromosome consists of two sister chromatids, when the cell divides the sister chromatids separate from each other, one goe to each of the two new cells.

Two tiny structures located in the cytoplasm near the nuclear envelope, they separtate and take up positions on opposite side of nucleus.

Each pair of chromatids is attached at an area called a centromere which is located in the middle of the chromatids

Regulates the timing of the cell cycle in eukaryotic cells.

The second phase of mitosis, chromosome line up across the cener of the cell, microtubules connect the centromere of each chromosome to the poles of the spindle.

Where the cytoplasm splits

Time when the cell is not dividing

Cell first copies its genetic information then it begins the process of cell division

1st stage in the process of cell division in eukaryotes.

A fanlike mirotubule structure that helps to separate the chromosomes

Series of events that cells go through as they grow and divide

Out of control cell division.

3rd phase of mitosis, the centromeres split allowing the sister chromatids to separate and become individual chromosomes.

The 4th and final phase of mitosis. nuclear envelope reforms, the spindle begins to break apart and a nucleolus becaomes visible in each daughter nucleus.
