Lipids

DNA

Proteins

The cell divides into two daughter cells through mitosis and cytokinesis

the cell grows, performs normal functions, and duplicates its DNA

The chromosomes condense and align at the cell's equator

The nuclear envelope breaks down and spindle fibers attach to chromosomes

To change the DNA sequence

To produce extra energy for cell division

To increase the cell's size before division

So each daughter cell receives an identical set of chromosomes

Interphase → Prophase → Metaphase → Telophase

Metaphase → Prophase → Anaphase → Telophase

Prophase → Metaphase → Anaphase → Telophase

Prophase → Anaphase → Metaphase → Telophase

Chromosomes condense, the nuclear membrane breaks down and spindle fibers form

the cytoplasm divides completing the formation of two separate daughter cells

chromosomes (sister chromatids) move to opposite poles of the cell

Chromosomes line up at the cell equator

What happens during cytokinesis?

The cytoplasm divides to form two separate cells

Chromosomes line up at the equator

Sister chromatids separate and move to opposite poles

Two identical copies of a single chromosome produced during DNA replication

A pair of chromosomes that carry the same genes in the same order — one inherited from each parent

A cell that has one of each type of chromosome

A group of four chromatids that forms during prophase I of meiosis
