Cell Division Vocabulary

Diploid

Cell with two of each kind of chromosome (2n number).

Haploid

A cell that contains one member of each chromosome pair (n number).

Anaphase

The phase of mitosis where the chromatids of each chromosome are pulled apart

Cell Cycle

Continuous sequence of growth and division in a cell...mitosis is just a small piece of the "pie" in this process.

G1 Phase

The phase of the Cell Cycle in which growth and replication of the organelles occur.

S Phase

The phase of the Cell Cycle in which DNA replication/synthesis occurs.

G2 Phase

The phase of the Cell Cycle in which the final preparations for Mitosis occur.

Centromere

Cell structure that holds the sister chromatids of a chromosome together.

Chromatin

Long strands (tangled masses) of DNA found in the nucleus that condense to form chromosomes just before cell division begins

Chromosomes

Cell structures that contain DNA and carry the genetic material from generation to generation

Cytokinesis

Cell process following mitosis in which the cell's cytoplasm divides and separates into new identical cells

Interphase

The cell growth phase where the cell increases in size and the chromosomes replicate. This is NOT technically a part of Mitosis and includes the G1, S, and G2 parts of the cell cycle.

Metaphase

The phase of mitosis where the chromosomes line up in the center (equator) of the cell

Mitosis

Nuclear cell division in which 2 daughter cells are formed..they are identical to the parent cell and have the same number of chromosomes

Prophase

The phase of mitosis in which chromatin condenses into visible chromosomes and jumble toward the center of the cell.

Cancer

Uncontrolled cell division that may be caused by environmental factors or by mitosis going haywire

Sister Chromatid

Identical half of a duplicated chromosome - the halves are held together by the centromere

Telophase

The final phase of mitosis where the cells have evenly distributed the chromosomes to each opposite end of the cell - cytokinesis happens immediately after this phase
