A sex cells for reproduction

General steps of mitosis involves:

All body cells, except those that give rise to sex cells, divide by_____.

The genetic material within the cell is _____.

Stages of Mitosis and Cell Division

It is the time between cell divisions.

_____ is found as thin threads of chromatin in the nucleus.

DNA Replication occurs during ______.

Each chromosome consists of two chromatids joined at the _______.

In ______, the chromatin condenses into chromosomes.

The centrioles move to the opposite ends of the cell, and the nucleolus and the nuclear envelope disappear.

Nuclear membrane breaks down Kinetochore microtubule invade nuclear space, and attached to kinetochore. Polar microtubules push against each other, moving centrosomes apart.

In________, the chromatids separate to form two sets of identical chromosomes.

______ invade nuclear space, and attached to kinetochore.

__________push against each other, moving centrosomes apart.

In _______, the chromosomes align in the center of the cell in association with the spindle fiber.

The chromosomes, assisted by the _______, move toward the centrioles at each end of the cell.

The nuclear envelopes and the nucleoli form.

In _______, the chromosomes disperse.

______is the physical process of cell division, which divides the cytoplasm of a parental cell into two daughter cells.
