Across
- 3. The process of division of somatic cells in which each daughter cell receives the same amount of DNA as the parent cell
- 5. The first phase of cell nucleus division, in which the chromosomes become visible, the cell nucleus starts to lose its identity, the mitotic spindle apparatus appears, and the centrioles migrate toward opposite poles
- 8. transduction The intercellular or intracellular transfer of information
- 9. The second phase of mitosis, in which the chromosomes line up across the equatorial plane of the spindle prior to separation
- 11. he segment at the end of each chromosome arm which consists of a series of repeated DNA sequences that regulate chromosomal replication at each cell division
- 12. The interval between two successive cell divisions during which the chromosomes are not individually distinguishable
- 14. Cleavage of the cytoplasm into daughter cells following nuclear division
- 17. Control center of a cell
- 18. Slender, cylindrical filaments found in the cytoskeleton of plant and animal cells
- 20. stem cells Stem cells that can become all the cell types that are found in an implanted embryo, fetus, or developed organism, but not embryonic components of the trophoblast and placenta
- 21. A sac-like compartment inside a cell that has enzymes that can break down cellular components that need to be destroyed
- 22. cycle The complete series of events from one cell division to the next
- 23. Fats
- 24. Any of the typically unicellular microorganisms that lack a distinct nucleus and membrane-bound organelles\
- 26. Kingdom that includes organisms composed of one or more cells containing visibly evident nuclei and organelles
- 27. A normal series of events in a cell that leads to its death
- 31. apparatus A stack of flattened vesicles that functions in posttranslational processing and sorting of proteins
- 32. The fluid inside a cell but outside the cell's nucleus
Down
- 1. A specific region or amino acid sequence in a protein associated with a particular function or corresponding segment of DNA
- 2. Any of the RNA- and protein-rich cytoplasmic organelles that are sites of protein synthesis
- 4. The phase of cell nucleus division following metaphase, in which the chromatids separate and migrate to opposite poles of the spindle
- 6. Surface ligands, usually glycoproteins, that mediate cell-to-cell adhesion
- 7. A sugar molecule
- 10. A small, membrane-bounded organelle that uses molecular oxygen to oxidize organic molecules
- 13. stem cells Bone marrow cells that (when signalled) mature into both red blood cells and white blood cells
- 15. clock A person's innate sense of time
- 16. adhesion Adherence of cells to surfaces or to other cells
- 18. Powerhouse of the cell
- 19. reticulum A system of interconnected vesicular and lamellar cytoplasmic membranes that functions especially in the transport of materials within the cell and that is studded with ribosomes in some places
- 24. cells Early descendants of stem cells that can differentiate to form one or more kinds of cells, but cannot divide and reproduce indefinitely
- 25. acids Any of various acids (as an RNA or a DNA) composed of nucleotide chains
- 28. The protein complement of an organism coded for by its genome
- 29. A molecule made up of amino acids that are needed for the body to function properly
- 30. cells Cells from which other types of cells can develop
