5 Written Questions

1. the period of the cell cycle during which the nucleus is not undergoing division, typically occurring between mitotic or meiotic divisions
2. chromosomes are replacated & the synthesis of DNA molecules takes place
3. second phase of mitosis, during which the chromosomes line up across the center of the cell (along the equitorial plate; spindles are attached to the centromeres)
4. disorder in which some of the body's own cells lose the ability to control growth; cells do not respond to the signals that regulate the growth of cells
5. area where the chromatids of a chromosome are attached

4 Matching Questions

1. external regulators
2. cell cycle
3. g2
4. cyclins

1. a during it, a cell grows, prepares for division and divides to form two new daughter cels, each of which begins the cycle again
2. b proteins that respond to events outside the cell, they direct cells to speed up or slow down the cell cycle. growth factors are the most important external regulators
3. c A group of proteins whose function is to regulate the progression of a cell through the cell cycle and whose concentrations rise and fall throughout the cell cycle
4. d The phase in interphase when the cell begins to form centrioles and other parts to prepare for cell division (mitosis)

5 Multiple Choice Questions

1. proteins that respond to events inside the cell; allow the cell cycle to proceed only when certatin processes have happened inside the cell
   1. centromeres
   2. external regulators
   3. internal regulators
   4. interphase
2. fourth and final phase of mitosis, during which the chromosomes begin to disperse into a tangle of dense material; a nuclear envelope forms, the spindle breaks apart, nucleolus forms in nucleus
   1. interphase
   2. prophase
   3. metaphase
   4. telophase
3. in eukaryotic cells, a process of cell division that forms two new nuclei, each of which has the same number of chromosomes
   1. mitosis
   2. metaphase
   3. cytokinesis
   4. cytokenisis
4. the process in reproduction and growth by which a cell divides to form daughter cells
   1. cyclins
   2. cytokenisis
   3. cell division
   4. cell cycle
5. consists of G1 phase, S phase, G2 phase and M phase
   1. S phase
   2. cell cycle
   3. centrioles
   4. telophase

5 True/False Questions

1. cytokinesis → division of the cytoplasm during cell division

   True        False

2. prophase → first and longest phase of mitosis, during which the chromosomes become visible and the centrioles separate and take up positions on the opposite sides of the nucleus

   True        False

3. spindle → chromosomes are replacated & the synthesis of DNA molecules takes place

   True        False

4. cytokenisis → takes place at the same time as telophase, think, THE BELT pinches at the center

   True        False

5. g1 → The phase in interphase when the cell begins to form centrioles and other parts to prepare for cell division (mitosis)

   True        False
