107539296 | Centriole | Cell organelle, existing in pairs, that occurs in the centosome and may help organize a mitotic spindle for chromosome movement during animal cell division | 10 | |

107539300 | Cyclin | Protein that cycles in quantity as the cell cycle progresses; combines with and activates the kinases that function to promote the events of the cycle. | 14 | |
107539301 | Cytokinesis | Division of the cytoplasm following mitosis and meiosis | 15 | |
107539302 | Diploid (2n) number | Cell condition in which two of each type of chromosome are present | 16 | |
107539303 | Haploid (n) number | Cell condition in which only one of each type of chromosome is present | 17 | |
107539304 | Interphase | Stages of the cell cycle (G1,S, G2) during which growth and DNA synthesis occur when the nucleus is not actively dividing | 18 | |
107539305 | Kinetochore | Disk-shaped structure within the centomere of a chromosome to which spindle microtubules become attached | 19 | |
107539306 | Leukemia | Cancer of the blood-forming tissues leading to the overproduction of abnormal white blood cells | 20 | |
107539307 | Metaphase | Mitotic phase during which chromosomes are aligned at the metaphase plate | 21 | |
107539308 | Metaphase Plate | A disk formed during metaphase in which all of a cell's chromosomes lie in a single plane at right angles to the spindle fibers | 22 | |
107539309 | Metastasis | Spread of cancer form the place of origin throughout the body; caused by the ability of cancer cells to migrate and invade tissues | 23 | |
107539310 | Mitosis | Process in which a parent nucleus produces two daughter nuclei, each having the same number and kinds of chromosomes as the parent nucleus | 24 | |
107539311 | Nucleoid | Region of prokaryotic where DNA is located; it is not | 25 | |
107539312 | Oncogene | Gene-causing gene | 26 | |
107539313 | Gene | Unit of heredity existing as alleles on the chromosomes; in diploid organisms, typically two alleles are inherited - one from each parent | 27 | |
107539314 | P53 Gene | For control for cell division the p5 gene halts the cell cycle when DNA mutates and is in need of repair | 28 | |
107539315 | Prometaphase | Mitotic phase during which the spindle is in process of forming, and kietochores of chromosomea are attaching to kinetochore spindle fibers. | 29 | |
107539316 | Prophase | Mitotic phase during which chromatin condenses so that chromosomes appear; chromosomes are scattered | 30 | |
107539317 | Proto-oncogene | Normal gene that can become an oncogene through mutation | 31 | |
107539318 | Sister chromatid | One of two genetically identical chromosomal units that are the result of DNA replication and are attached to each other at the centromere | 32 | |
107539319 | Somatic Cells | Body Cell; Excludes cells that undergo meiosis and become sperm or egg | 33 | |
107539320 | Somatic System | Portion of the peripheral nervous system containing motor neurons that controls skeletal muscles | 34 | |
107539321 | Spindle | Microtubule structure that brings about chromosomal movement during nuclear division | 35 | |
107539322 | Telomere | Tip of the end of a chromosome that shortens with each cell division and may thereby regulate the number of times a cell can divide | 36 | |
107539323 | Telophase | Mitotic phase during which daughter cells are located at each pole | 37 | |
107539324 | Tumor | Cells derived from a single mutated cell that has repeatedly undergone cell division; benign tumors remain at the site of origin, while malignant tumors metastasize. | 38 | |
107539325 | Tumor-suppressor gene | Gene that codes for a protein that ordinarily suppresses cell division; inactivity can lead to a tumor | 39 |
