|
Term
|
Definition
Following replication a chromosome consists of a pair of sister chromatids, each a single DNA helix, held together at the centromere. Following separation, each chromosome is a single chromatid. |

Term
|
Definition
Network of DNA strands and associated proteins observed within a nucleus that is not dividing. |
|
|
Term
|
Definition
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. |

|
Term
|
Definition
Division of the cytoplasm following mitosis or meiosis. |

Term
|
Definition
Cell condition in which two of each type of chromosome are present. |
|

Term
|
Definition
A hormone or chemical, secreted by one cell, that may stimulate or inhibit growth of another cell or cells. |

Cell condition in which only one of each type of chromosome is present. |
|
|
Term
|
Definition
A group of proteins involved in forming the nucleosome structure of eukaryote chromatin. |
|
|
Term
|
Definition
Stages of the cell cycle (G1, S, G2) during which growth and DNA synthesis occur when the nucleus is not actively dividing. |

Term
|
Definition
The power to threaten life; cancerous. |
|
|
Term
|
Definition
Mitotic phase during which chromosomes are aligned at the metaphase plate. |
|
|
Term
|
Definition
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. |
|
|
Term
|
Definition
Spread of cancer from the place of origin throughout the body; caused by the ability of cancer cells to migrate and invade tissues. |
|
|
Term
|
Definition
Process in which a parent nucleus produces two daughter nuclei, each having the same number and kinds of chromosomes as the parent nucleus. |
|
|
Term
|
Definition
Microtubule structure that brings about chromosomal movement during nuclear division. |
|
|
Term
|
Definition
Region of prokaryotic cells where DNA is located; it is not bounded by a nuclear envelope. |
|
|
Term
|
Definition
Cancer-causing gene. Oncogenes code for proteins that stimulate the cell cycle and inhibit apoptosis. |
|
|
Term
|
Definition
Phase of mitosis during which the chromosomes are condensed but not fully aligned at the metaphase plate. |
|
|
Term
|
Definition
Mitotic phase during which chromatin condenses so that chromosomes appear; chromosomes are scattered. |
|
|
Term
|
Definition
Normal gene that can become an oncogene through mutation. |
|
|
Term
|
