Across
- 2. any of a number of proteins associated with the cycle of cell division which are thought to initiate certain processes of mitosis
- 3. the final phase of cell division, between anaphase and interphase, in which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed
- 6. a substance, such as a vitamin or hormone, which is required for the stimulation of growth in living cells
- 8. an undifferentiated cell of a multicellular organism which is capable of giving rise to indefinitely more cells of the same type, and from which certain other kinds of cell arise by differentiation
- 9. able to do everything, to develop into any type of cell in the body
- 11. The production of offspring by combining genetic information from two parents (male and female) that inherits different traits
- 12. a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus
- 13. the resting phase between successive mitotic divisions of a cell
- 14. the second stage of cell division, between prophase and anaphase, during which the chromosomes are lines up in the middle of the cell and become attached to the spindle fibers
- 17. an unborn or unhatched offspring in the process of development, in particular a human offspring during the period from approximately the second to the eighth week after fertilization
- 18. can develop into most, but not all, of the body’s cell types
- 20. the cytoplasmic division of a cell at the end of mitosis
- 21. A threadlike structure of nucleic acids and protein found in the nucleus that carries genetic information in the form of genes
- 22. a disease caused by an uncontrolled division of abnormal cells in a part of the body
- 24. A complex of DNA and protein/histones found in eukaryotic cells
- 25. each of the two threadlike strands into which a chromosome divides longitudinally during cell division
- 26. the first stage of cell division, before metaphase, during which the chromosomes become visible as paired chromatids and the nuclear envelope disappears
Down
- 1. the region of a chromosome to which the microtubules of the spindle attach
- 2. During the cell cycle, a cell grows, prepares for division, and divides to form two daughter cells
- 4. Process by which cells become specialized
- 5. a hollow ball of cells with a cluster of cells inside known as the inner cell mass
- 7. the death of cells which occurs as a normal and controlled part of an organism's growth or development
- 10. a minute cylindrical organelle near the nucleus in animal cells, occurring in pairs and involved in the development of spindle fibers in cell division
- 15. The production of genetically identical offspring from a single parent
- 16. can develop into many types of differentiated cells
- 19. a swelling of a part of the body, generally without inflammation, caused by an abnormal growth of tissue, whether benign or malignant
- 22. The process by which a cell divides into two new daughter cells
- 23. the stage of mitotic cell division in which the chromosomes move away from one another to opposite poles of the spindle
