5 Matching questions

  1. metaphase
  2. anaphase
  3. desmosome
  4. interphase
  5. cell division
  1. a Anchoring junctions that prevents cells subjected to mechanical stress from being pulled apart; two adjacent cells are attached. formed from protein plaques in the the cell membranes linked by protein filaments
  2. b Second Stage of Cell division: Centromeres of duplicated chromosomes are aligned at plate. chromosomes become attached to spindle fibers
  3. c A the resting phase between two mitotic or meiotic divisions during which the cell grows, copies its DNA, and synthesizes proteins
  4. d 3rd phase; the chromatids of each chromosome separate at the centromere and move in opposite poles of the spindle.
  5. e Process by which a cell divides into two new daughter cells

5 Multiple choice questions

  1. A substance produced by a living organism that acts as a catalyst to bring about a specific chemical reaction
  2. Cells are tightly bound, prevent fluids and most molecules from moving between cells. Useful in places such as the stomach and kidneys. types are desmosomes, tight junctions, and gap junctions
  3. A threadlike, gene-carrying structure found in the nucleus. consists of one very long DNA molecule and associated proteins.
  4. biological unit of hereditary information located in chromatin consisting of a specific nucleotide sequence in DNA (or RNA, in some viruses). that transmits hereditary information.
  5. After the chromosome seperates, the cell seals off, Final Phase of Mitosis., A cleavage furrow forms during this phase, two nuclei are formed
