|
Chromosome |
Long continuous thread of DNA that consists of numerous genes along with regulatory information. |
|
|
Histone |
The protein that a chromosome is associated with. |
|
|
Chromatin |
Loose combination of DNA and proteins. |
|
|
Chromatid |
One half of a duplicated chromosome. |
|
|
Centromere |
Where the sister chromosomes are held together. |
|
|
Telomere |
Repeating nucleotides at the end of DNA molecules that do not form genes. They prevent chromosomes from accidentally touching eachother. |
|
|
Prophase |
Chromatin condenses into chromosomes, each one consists of two sister chromatids. |
|
|
Metaphase |
Chromosomes allign at the equator of the cell. |
|
|
Anaphase |
Sister chromatids seperate. Spindle fibers pull them from center to the outside of the cell on opposite sides. |
|
|
Telophase |
Nuclear membrane forms, cell starts to split. |
|
|
Growth Factors |
A broad group of proteins that stimulate cell division. |
|
|
Apoptosis |
Programmed cell death. |
|
|
Cancer |
Uncontrolled cell division. |
|
|
Benign Tumor |
Cells remain clustered together. |
|
|
Malignant Tumor |
Cancer cells break away or metastasize from the tumor. |
|
|
Carcinogens |
Subastances known to promote the development of cancer. |
|
|
Homologus Chromosomes |
Two chromosomes, one from the mother, one from the father, that have the same length and general appearence. |
|
|
Meiosis |
A form of nuclear divison that divides a diploid cell into a haploid cell. |
|
|
Meiosis I |
Produces two haploid cells with duplicated chromosomes. |
|
|
Meiosis ll |
Produces 4 haploid cells. |
|
|
Gametogenesis |
Production of gametes. |
|
|
Polar Bodies |
Cells eventually broken down. |
|
|
Purebread |
Genetically Uniform |
