CELL CYCLE 2026/2027 QUESTIONS AND SOLUTIONS
RATED A+
✔✔chromosome - ✔✔A doubled rod of condensed chromatin; contains DNA that carries
genetic information
✔✔centromere - ✔✔Area where the chromatids of a chromosome are attached
✔✔cell cycle - ✔✔An ordered sequence of events in the life of a eukaryotic cell; process
of growth and division.
✔✔G1 phase - ✔✔interphase stage of cell cycle where cell grows and carries out
metabolic processes
✔✔G2 phase - ✔✔interphase stage prepares to divide by copying organelles
✔✔S phase - ✔✔interphase stage of cell cycle where cell replicates DNA
✔✔Mitosis - ✔✔stage of cell cycle where the nucleus divides
✔✔Interphase - ✔✔Majority of cell cycle is in this stage
✔✔Checkpoints - ✔✔stop to the cell cycle to check for damage
✔✔Cancer - ✔✔Cells skip checkpoints and divide uncontrollably
✔✔Prophase - ✔✔first stage of mitosis, nuclear envelope disappears, chromosomes
condense
✔✔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.
