Across
- 2. dna condensed through histone wrapping, and must be further condensed into chromosomes
- 3. When the cell prepares to divide
- 6. Division of the nucleus
- 9. protein Found in eukaryotic cell nuclei, packages and orders dna into structural units; nucleosomes
- 10. Present in cytoplasm
- 11. chromosomes Single chromatids
- 15. Special groups of proteins specifically involved in attachment of spindle fibers
- 16. pair Chromosomes containing maternal and paternal chromatid joined together at the centromere
- 17. Seperated chromosomes move towards the poles
- 18. Replicated chromosomes line up at the equatorial plate
- 20. Numerical arrangement of chromosomes by size
- 23. part of cell division; nuclear division in eukaryotic somatic cells
- 25. Most constricted point of chromosome; where spindle fiber attach during mitosis
- 26. fibers Fibers shaped like a star, formed around each chromosome
- 27. plate Plate that develops at the midpoint between two groups of chromosomes in dividing cell, and involved in forming a wall
- 28. chromosomes Two identical chromosomes that result from dna replication
- 30. /Alternative of programmed cell death
- 32. phase Cell cycle arrest
Down
- 1. Division of cytoplasm
- 4. Controlling excessive, rapid speed
- 5. Organelle near the nucleus in animal cells
- 7. Chromosomes move to opposite ends of the cell and two nuclei are formed
- 8. chromatids Identical copies of one chromatid in a replicated chromosome
- 12. phase Cell prepares to divide the nucleus
- 13. Half of replicated chromosomes
- 14. Chromosomes become visible and the nucleus disappears
- 19. fibers Form protein structure that divides genetic material
- 21. filament Thin fibers composed of a protein called actin
- 22. replication Double-stranded molecule is copied to produce two identical dna molecules
- 24. phase Synthesis; cell copies dna
- 29. furrow Indentation of cell's surface
- 31. Number of complete sets of chromosomes in the nucleus of a cell
