A four-stage process that creates two identical cells from one original cell; the process in which a eukaryotic cell nucleus splits in two, followed by division of the parent cell into two daughter cells.

Deoxyribonucleic acid; a substance that carries genetic information in the cells of plants and animals; a double-stranded nucleic acid that contains the genetic information for cell growth, division, and function.

A period of cell growth and normal activity. This period comes between mitosis cycles. Cells that do not need to replicate will spend their time in this stage. If a cell does need to divide, it will copy all of it's DNA while in this period.

-the thread-like structures into which the DNA molecule is packaged in the nucleus of each cell. Each is made up of DNA tightly coiled many times around proteins called histones that support its structure.

The first and longest stage of mitosis. In this stage the chromosomes become visible and the centrioles separate and move to opposite poles of the cell.

-the process of producing two identical replicas from one original DNA molecule. This biological process occurs in all living organisms and is the basis for biological inheritance.

-The second stage of mitosis. In this stage the chromosomes line up across the center of the cell and become connected to the spindle fiber at their centromere.

The fourth and last stage of mitosis. During this stage the chromosomes gather at opposite ends of the cell and lose their distinct rod-like shapes. Two new nuclear membranes then form around each of the two regions of DNA and the spindle fibers disa

The third stage of mitosis. In this stage the sister chromatids separate into individual chromosomes and are pulled apart.

The process following the last stage of mitosis. With two complete copies of the DNA now in two different regions of one cell, the cell membrane will pinch and divide the cytoplasm in half resulting in two cells identical to the parent cells.

Name the 4 phases of mitosis (cell division)

two or more cells formed in the division of a parent cell.

New organisms produced by a living thing.
