Mitosis and Cytokinesis – Flashcards

Cell structures made up of both centrioles and individual microtubule fibers that are involved in moving chromosomes during cell division

An organelle that organizes the assembly of the spindle

The process during cell division in which the nucleus of a cell is divided into two nuclei

The process during cell division in which the cytoplasm divides. The cell membrane grows to enclose each cell, forming two separate cells.

Structure in animal cells from whence spindle fibers come

Phase of mitosis in which chromosomes coil up an become visible. The nuclear envelope dissolves and a spindle forms.

Phase of mitosis in which chromosomes move to the center of the cell and line up along the equator. Spindle fibers link the chromatids of each chromosome to opposite poles.

Phase of mitosis in which centromeres divide. The two chromosomes move toward opposite poles as the spindle fibers attached to them shorten

Phase of mitosis in which a nuclear envelope forms around the chromosomes at each pole. Chromosomes, now at opposite poles, uncoil and the spindle dissolves. The spindle fibers break down and disappear. Mitosis is complete.

DNA in nucleus during interphase

One of two identical strands into which a chromosome splits during mitosis

The first sign of cleavage in an animal cell; a shallow groove in the cell surface near the old metaphase plate.

A specialized condensed region of each chromosome that appears during mitosis where the chromatids are held together to form an X shape

An imaginary plane during metaphase in which the centromeres of all the duplicated chromosomes are located midway between the two poles
