CELL CYCLE EXAM SCRIPT 2026/2027 QUESTIONS AND
SOLUTIONS RATED A+
✔✔Metaphase - ✔✔second stage of mitosis, centrioles move to opposite ends of cell,
spindle fibers attach to chromosomes, chromosomes line up in middle
✔✔Anaphase - ✔✔third stage of mitosis, spindle fibers shorten pulling chromosomes
apart
✔✔Telophase - ✔✔fourth stage of mitosis, cells begin to form cleavage furrow (animal)
or cell plate (plant) and divide
✔✔Cytokinesis - ✔✔final stage of the cell cycle, cells divide and move apart
✔✔Prophase diagram - ✔✔DNA fist condenses and forms chromosomes
✔✔Metaphase diagram - ✔✔Chromosomes line up at the equator of the cell.
✔✔Anaphase diagram - ✔✔Sister chromatids get pulled apart
✔✔Telophase diagram - ✔✔Two nuclei start to re-form, cleavage begins to form.
✔✔Cytokinesis diagram - ✔✔The division of the cytoplasm.
✔✔Chromosome - ✔✔Condensed DNA
✔✔Centromere - ✔✔central part of chromosome, joining the two sister chromatids
✔✔Chromatid - ✔✔single copy of DNA strands
✔✔Centriole - ✔✔organelle the sends out spindle fibers
✔✔Spindle fiber - ✔✔emerge from centrioles, attach to chromosomes to pull them apart
during mitosis
✔✔Purpose of mitosis - ✔✔divides cells that are too large, replaces damaged/dying
cells, allows for growth
✔✔Cleavage furrow - ✔✔a pinching of the cell membrane that begins to form in
telophase
✔✔Carcinogens - ✔✔tobacco, radiation, UV exposure, etc.
