BIOD 101 MODULE 4 STUDY SHEET 2026
EXAM QUESTIONS AND ANSWERS EXPERT
VERIFIED
◉Characteristics of telophase. Answer: 1. reformation of nuclei,
some organelles, and nuceoli
2. decondensing of chromosomes
3. dissolution of spindle microtubules
4. mitotic phase completion
5. Cytokinesis
◉Cleavage. Answer: Process through which cytokinesis occurs in
animal cells
◉Cleavage furrow. Answer: visible groove along metphase plate of
cell. Actin and myosin interact to contract actin ring like a
drawstring and divide the cell
◉Cell cycle control system. Answer: molecular surveillance
mechanisms that can halt the cell cycle or allow it to proceed
, ◉Checkpoints. Answer: places along the cycle where processes are
halted and mechanisms are deployed to ensure cell is ready to
proceed to next phase
◉cycle locations of checkpoints. Answer: G1+S, G2+M,
metaphase+anaphase
◉phosphorylation. Answer: chemical addition of a phosphate group
◉protein kinases. Answer: enzymes that phosphorylate other
proteins to activate or inactivate them
◉cyclin. Answer: protein that fluctuates in concentration at different
phases of the cycle
◉-dependent kinases (Cdks). Answer: depend on presence of cyclins
to become active or inactive
◉MPF (maturation-promoting factor). Answer: A cyclin-Cdk
complex that causes the cell to move from interphase into mitosis.
◉G1 checkpoint. Answer: major checkpoint, cell is committed to
division after passing
