| Term | Definition |
|---|---|
| cell cycle | regular pattern of growth, DNA duplication, and cell division that occurs in eukaryotic cells |
| mitosis | division of the cell nucleus and the DNA inside it |
| cytokinesis | division of the contents of the rest of the cell, the cytoplasm |
| chromosome | one long piece of DNA, your body cells have 46 of these |
| chromatid | half of a duplicated chromosome |
| centromere | place where the sister chromatids together |
| histone | proteins that DNA wraps around |
| chromatin | formed when the DNA wraps around histones |
| telomere | helps prevent the loss of genes |
| prophase | duplicated chromosomes are formed and the nuclear membrane starts to break down |
| metaphase | chromosomes line up in the middle of the cell |
| anaphase | sister chromatids separate to opposite sides of the cell |
| telophase | nuclear membrane starts to form again and chromosomes start to uncoil |
| growth factors | proteins that stimulate cell division |
| apoptosis | programmed cell death |
| cancer | common name for a group of diseases that involve uncontrolled cell division |
| benign | harmless tumor |
| malignant | tumor that has cancer cells |
| metastasize | when cancer cells break away from the tumor and spread to other parts of your body |
| carcinogens | substances known to cause cancer |
| asexual reproduction | production of offspring from a single parent |
| binary fission | asexual reproduction of a single-celled organism by division into two parts |
| tissues | groups of cells that work together to perform a similar function |
| organs | groups of tissues that work together to perform specific functions |
| organ systems | groups of organs that work together |
| cell differentiation | process by which cells that are not specialized develop into their specialized forms |
| stem cells | special type of body cell that can develop inot different types of cells |
