Across
- 4. one of two identical "sister" parts of a duplicated chromosome
- 5. a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes
- 7. a mass of abnormal cells that remain at the site of origin
- 8. A cell containing only one set of chromosomes (n), examples: sperm and egg
- 10. phase of mitosis in which the distinct individual chromosomes begin to spread out into a tangle of chromatin, 2 nuclear envelopes form, nucleolus becomes visible
- 12. in-between period of the cell cycle between cell divisions includes G1, S, and G2
- 14. any cell of a living organism other than the reproductive cell, 2n
- 15. sec cells
- 16. series of events that cells go through as they grow and divide
- 18. A cell containing two sets of chromosomes (2n), one set inherited from each parent example: somatic or body cells
Down
- 1. Cells that do not contain nuclei, reproduce asexually and use haploid cells
- 2. division of the cytoplasm to form two separate daughter cells plant cells: cell plate and animal cells: cleavage furrow
- 3. Cells that enclose their DNA in nuclei, reproduce both asexually and sexually, use both haploid and diploid cells
- 5. granular material visible within the nucleus; consists of DNA tightly coiled around proteins
- 6. Division of the nucleus
- 9. the third phase of mitosis, during which the chromosome pairs separate and move toward opposite poles
- 11. first and longest phase of mitosis, during which the chromosomes become visible and the centrioles separate and take up positions on the opposite sides of the nucleus
- 13. any cell of a living organism other than the reproductive cell, 2n
- 17. is one of a family of proteins that regulates the cell cycle in eukaryotic cells
