genetic material of the eukaryotic nucleus 4. chromosome- condensed threads of genetic material formed from chromatin as a cell prepares to divide 5. sister chromatid- one of a pair of identical chromosomes created before a cell divides 6. centromere- region where two sister chromatids are joined together 7. cell cycle- sequence of events from the production of a eukaryotic cell to the time the cell itself reproduces 8. interphase- stage of the cell cycle during which a cell carries out its metabolic processes and performs its functions in the body 9. mitotic phase- stage of the cell cycle when a cell is actively dividing 10. mitosis- a nucleus and duplicate chromosomes of a cell divide and are evenly distributed, forming two daughter nuclei 11. cytokinesis- process by which the cytoplasm of a cell is divided into two; usually follows mitosis or meiosis 12. prophase- first stage of mitosis and of meiosis I and II, when the already replicated chromosomes condense 13. metaphase- second stage of mitosis and of meiosis I and II when the spindle is fully formed and all of the chromosomes are held in place 14. anaphase- third phase of mitosis and of meiosis I and II, in which the sister chromatids separate and move toward the poles of the spindle 15. telophase- final stage of mitosis and of meiosis I and II, in which the chromosomes reach the spindle poles, nuclear envelopes form around each set of daughter chromosomes, and the nucleoli reappear 16. benign tumor- mass of cells that remain at their original site 17. malignant tumor-mass of abnormal cells resulting from uncontrolled canceer cell division 18. cancer- disease caused by severe disruption of the mechanisms that normally control the cell cycle 19. metastasis- spread of cancer cells beyond their original site in the body 20. meiosis- type of cell division that produces 4 cells, each with half as many chromosomes as the parent cell 21. karyotype- display of a person's 46 chromosomes 22. homologous chromosome- one of a matching pair of chromosomes, one inherited from each parent 23. sex chromosome- one of the two chromosomes of the 23rd pair of human chromosomes which determine an individual’s gender 24. diploid- having two homologous sets of chromosomes 25. gamete- egg or sperm sex cell that contains a single of chromosomes, one from each homologous pair 26. haploid- having a single set of chromosomes 27. fertilization- the fusion of the nucleus of a haploid sperm cell and the nucleus of a haploid egg cell, forming a diploid zygote 28. zygote- diploid cell formed when the nucleus of a haploid sperm cell fuses with the nucleus of a haploid egg cell 29. crossing over- exchange of genetic material between homologous chromosomes during prophase I of meiosis 30. genetic recombination- new combination of genetic information in a gamete as a result of crossing over during prophase I of meiosis 31. spindle- framework of microtubules that guide the movement of chromosomes during mitosis and meiosis Chapter 9: Cellular Basis for Inheritance You will need to work the following vocabulary on a separate sheet of paper: #1-6, & #21-31. 1. asexual reproduction- process in which a single cell or set of cells produces offspring that inherit all their genetic material from one parent 2. sexual reproduction- process in which genetic material from two parents combines and produces offspring that differ genetically from either parent 3. chromatin-DNA and protein molecules in long, thin fibers;
