Across
  1. 5. The first part of the cell cycle and its purpose is to produce replicated and synthesized DNA for cell division.It is the longest portion of the cell cycle. There’s
  2. 7. DNA replication and chromosome duplication occurs
  3. 8. - Body Cells, Diploid (two sets of chromosomes) Divide by Mitosis
  4. 11. portions to the interphase (90%).
  5. 13. Before cell division, cells must organize and package their DNA before division.
  6. 14. This consists of two sections - Mitosis and cytokinesis.
  7. 16. Factors hormones that are released by cells that stimulate cell growth, the signal transduction pathway is started. CDKs activate which leads to cell cycle progression
  8. 18. - A protein in centromere where spindle fibers attach to during mitosis/meiosis
  9. 19. - Reproductive Cells (eggs/sperm), Haploid (one set of chromosomes) Divide by Meiosis
  10. 20. Two daughter nucleus, chromosomes less condensed
  11. 24. - A region in the middle of a chromosome, dividing it into two parts
  12. 25. Chromatin begin to thicken, Nucleoli disappear, and the spindle fibers begin to form
  13. 26. Animals: cleavage furrow forms and splits cell. Plants: cell plate form and splits cell
  14. 27. Enzymes that get activated by a specific cyclin which have specific effects that regulate key events in the cell cycle
Down
  1. 1. Fibers - long strands of protein that move to each side of the cell
  2. 2. Sister chromatids (two identical chromatids) separate and go to opposite sides, cell gets longer
  3. 3. Things that make sure the cell cycle is functioning correctly and nothing is going on. Regulation in a cell involves internal control systems that consist of the following…
  4. 4. dependence Attaches to other cells or the extracellular matrix in order for cell division to occur
  5. 6. A protein involved in regulation in the cell cycle
  6. 9. - Located in the nucleus, made up of proteins and DNA organized into genes.
  7. 10. It is a cancer of the body's blood-forming tissues, including the bone marrow and the lymphatic system. In simple terms, cancer is defined as the uncontrolled growth of abnormal cells.Many types of leukemia exist. Some forms of leukemia are more common in children. Other forms of leukemia occur mostly in adults. Leukemia usually involves the white blood cells. Bone marrow makes blood cells so if theyŕe negatively affected by cancer, new blood cells cannot be created leading to only abnormal cells remaining. All cancers do not regulate the Cell Cycle and that is how they are all similar. New cells aren’t created so only the abnormal cells are left.
  8. 12. -A type of protein found in chromosomes. Histones bind to DNA, help give chromosomes their shape, and help control the activity of genes
  9. 15. - “subunit” of chromatin Nucleosomes are made up of DNA wrapped around histone complexes in a pattern that is universal only in eukaryotic cells.
  10. 17. Centrosomes on opposite sides, chromosomes lined up in center, microtubules attached to kinetochore
  11. 19. cell grows and carries out normal cellular functions
  12. 21. - a structure in a chromosome which holds DNA and protein. Stores all DNA and Protein in cells.
  13. 22. It is defined as the life of a cell from its formation until its division. More simply, a series of events that takes place in a cell as it grows and divides.
  14. 23. when nucleus divides
