Across
- 1. unspecialized cells that retain the ability to become a wide variety of specialized cells.
- 5. Area where the chromatids of a chromosome are attached.
- 6. Programmed cell death.
- 9. one of a group of external regulatory proteins that stimulate the growth and division of cells.
- 11. Cells that are capable of developing into most, but not all, of the body's cell types.
- 13. The ability to sort out and use independently different parts of the body in a specific and controlled manner.
- 14. "The events of cell division; includes interphase, mitosis, and cytokinesis”.
- 16. A mass of abnormal cells that develops when cancerous cells divide and grow uncontrollably.
- 18. Process of reproduction involving a single parent that results in offspring that are genetically identical to the parent.
- 22. "Final phase of mitosis during which chromosomes uncoil, a nuclear envelope returns around the chromatin, and a nucleolus becomes visible in each daughter cell”.
- 23. a cell that can turn into some of the cells.
- 25. Phase of mitosis in which the chromosomes separate and move to opposite ends of the cell.
- 26. Cell organelle that aids in cell division in animal cells only.
Down
- 2. A cellular structure carrying genetic material, found in the nucleus of eukaryotic cells. Each chromosome consists of one very long DNA molecule and associated proteins.
- 3. stage of early development in mammals that consists of a hollow ball of cells.
- 4. When the chromosome align connected to the spindle fibers.
- 5. Process by which a cell divides into two new daughter cells.
- 7. one of a family of closely related proteins that regulate the cell cycle in eukaryotic cells.
- 8. Disorder in which some of the body's cells lose the ability to control growth.
- 10. Division of the cytoplasm during cell division.
- 12. A reproductive process that involves two parents that combine their genetic material to produce a new organism, which differs from both parents.
- 14. Substance found in eukaryotic chromosomes that consists of DNA tightly coiled around histones.
- 15. one of two identical "sister" parts of a duplicated chromosome.
- 17. Stem cells with the potential to differentiate into any type of cell.
- 19. A process of nuclear division in eukaryotic cells conventionally divided into five stages: prophase, pro-metaphase, metaphase, anaphase, and telophase. Mitosis conserves chromosome number by equally allocating replicated chromosomes to each of the daughter nuclei.
- 20. stage of the eukaryotic cell cycle when the cell grows, synthesizes DNA, and prepares to divide.
- 21. An organism in the earliest stage of development.
- 24. Chromosomes become visible, nuclear envelop dissolves, spindle forms.
