Mitosis and Cell Cycle Notes

1st stage of cell division

interphase

What happens during telophase?

- (t)wo nuclei form - chromosomes appear as chromatin (threads rather than rods) - mitosis ends

What happens during cytokinesis?

- cell membrane moves inward to create two daughter cells -- each with its own nucleus with identical chromosomes during the last stage there are 2 different cells (c)ytokinesis = (c)ytoplasm divides in town

What happens during metaphase?

- chromatids (pairs of chromosomes) attach to the spindle fibers --- and line up in the middle of the cell the nucleus is gone so there is no room to move

What happens during anaphase?

- chromatids separate and begin to move to opposite ends of the cell (a)naphase = chromatids move (a)part

What happens during interphase?

- chromosomes are copied - chromosomes appear as threadlike coils (like pasta) at the beginning, but each chromosome and its copy (sister) change to sister chromatids at the end of this phase.

Be able to label the stages of the cell cycle.

______ organisms use mitosis to grow and repair themselves.

All

What happens during prophase?

PRO = first (step) - mitosis begins (cells divide) - centrioles appear and begin to move to opposite ends of cell - spindle fibers form between the poles - DNA condenses into chromosomes (X)

______ organisms use mitosis to reproduce asexually (no sperm or egg, only one parent)

Some

What is mitosis?

The process in which cells divide to make new cells.

What is the cell cycle?

The series of events that takes place in a cell leading to its division.

cell division

all cells go through this process

4th stage of cell division

anaphase

When bacteria reproduce, it is asexual or sexual reproduction?

asexual reproduction

6th stage of cell division

cytokinesis

3rd stage of cell division

metaphase (m)etaphase (middle)

2nd stage of cell division

prophase

5th stage of cell division

telophase

How do bacteria reproduce?

using mitosis
