Across
- 3. cycle the complete life cycle of a cell: interphase, mitosis, cytokinesis
- 5. the two identical copies of DNA that make up a chromosome during mitosis
- 6. the process by which a cell divides into two smaller cells
- 9. sister chromatids pull apart and move to opposite ends of the cell; chromatids now become chromosomes
- 11. spindle fibers attach to centromeres of chromosomes; chromosomes align down the middle of the cell
- 13. fibers fiber-like structures in a cell that are involved in moving chromosomes during cell division
- 15. having cells with membrane bound nuclei
- 16. chromosomes the two chromosomes from each parent that are similar in size, shape, and genetic content; there are 23 pair of homologous chromosomes in human body cells (23 from our mother, 23 from our father)
- 17. reproduction reproduction in which TWO haploid cells fuse to form a diploid cell; the zygote has a combination of traits (NOT IDENTICAL) compared to its parent cells
- 18. 90% of the life of the cell; cell carries out its normal functions; divided into 3 phases: (G1) First growth, (S) Synthesis, (G2) Second growth
Down
- 1. an organism or cell having the normal amount of DNA per cell
- 2. cell division that produces reproductive cells
- 4. reproductive cells formed by meiosis; sperm and egg; contain the organisms’ haploid number of chromosomes
- 5. final stage of the cell cycle; cytoplasm divides and creates two identical cells
- 7. reproduction reproduction in which a cell makes and IDENTICAL copy of itself; ex: binary fisson, mitosis
- 8. the DNA and its proteins in eukaryotic cells
- 10. two new nuclei form and nuclear envelope surrounds them; chromosomes uncoil; spindles dissolve
- 12. a specialized condensed region of each chromosome that appears during mitosis where the chromatids are held together to form an X shape
- 14. a fertilized egg; the first diploid cell on an individual containing DNA from both parents
- 19. the first stage of meiosis
