Mitosis Vocab. 1. Chromosome- package of DNA & proteins that stores genetic information and “tells” cell how to function. 2. Chromatid – One part of a chromosome 3. Spindle fibers- protein filaments (part of cytoskeleton) that move the chromosomes apart during cell division. 4. chromatin- uncoiled DNA; visible in interphase 5. centromere- “merely in the center” of chromosome- holds chromatids together 6. centriole- Only in ANIMAL cells during cell division. Act as support “poles” to aid in movement of chromosomes. 7. nuclear envelope- 8. equator (cell)9. poles (cell)- 10. DNA- Deoxyribonucleic AcidSegments of genes that control organism’s traits 11. Daughter cells- 2 identical cells with the same # of chromosomes as original cell (products of mitosis) 12. cytokinesis- Final step of cell cycle; process of cytoplasm dividing to form 2 new cells.
