  1. 3. The molecule that carries genetic information in living organisms, consisting of two strands that form a double helix.
  2. 5. The protein structures that help move chromosomes during cell division by pulling them toward opposite ends of the cell.
  3. 7. A thread-like structure composed of DNA and proteins that carry genetic information in the form of genes.
  4. 9. The series of events that take place in a cell leading to its division and duplication, including interphase and mitosis.
  5. 10. A cylindrical structure found in animal cells that helps organize the spindle fibers during cell division
  6. 11. The phase of the cell cycle in which the cell grows, replicates its DNA, and prepares for mitosis. It consists of G1, S, and G2 phases.
  7. 12. The stage of mitosis where chromosomes align along the center of the cell before being separated
  8. 13. The region of a chromosome where two sister chromatids are joined and where spindle fibers attach during mitosis.

  1. 1. The final stage of cell division, where the cytoplasm divides and two daughter cells are formed.
  2. 2. The phase of mitosis when sister chromatids are pulled apart toward opposite poles of the cell.
  3. 4. The process of cell division that results in two genetically identical daughter cells.
  4. 6. The first stage of mitosis when chromatin condenses into visible chromosomes, and the nuclear membrane begins to break down.
  5. 7. The uncondensed form of DNA and proteins found in the nucleus of a cell during interphase, before it condenses into chromosomes.
  6. 8. The stage of mitosis when the chromosomes reach opposite poles, and the nuclear envelope reforms around them.
  7. 9. The structure that forms in plant cells during cytokinesis, dividing the two daughter cells.
  8. 13. The two identical halves of a chromosome formed after DNA replication, connected by a centromere.
