1Cell Cycle, Cell Differentiation, & GMOs Hot Seat
2If an organism reproduces asexually, its offspring will most likely be Genetically identical to the parentGenetically different from each otherproduced as a result of fertilizationproduced from specialized cells known as gametes
9During what stage of the cell cycle is the DNA copied? M
10Once mitosis and cytokinesis are complete, what part of the cell cycle do the daughter cells enter?
11During which phase of the cell cycle does a cell grow and prepare for mitosis?
12During which phase of the cell cycle does a cell grow and add organelles? M
13The uncontrolled division of certain body cells, which then invade the surrounding tissues and interfere with the normal functioning of the body, is known ascancermitosiscytokinesisCleavage
14If a cell is not dividing, where will it be in the cell cycle?
15Which type of cell has the potential to produce any type of specialized cell? stem cells
16When unspecialized stem cells give rise to specialized cells, what is this process called? DifferentiationOsmosisMitosisMeiosis
17A liver cell and a skin cell from the same person have the same OrganellesDNAFunctionShape
18What makes stem cells different from other cells in the body? They are larger than other cells, and can absorb broken cells to repair them.They repair cells by breaking open and making their cell parts available for absorption into other cells.They are undifferentiated cells that can turn into a number of different kinds of cells, as needed.
19Which of the following is mitosis not used for? Repair (of a wound) in multicellular organismsAsexual reproduction in unicellular organismsDevelopment (e.g., baby in mother's womb)Production of gametes (sperm and egg)All of the above use mitosis
20The stage of the cell cycle where each chromosome is composed of two chromatids in preparation for mitosis.G1SG2M
21During _______ both the contents of the nucleus and the cytoplasm are divided.
22A cell has 5 chromosomes in G1 A cell has 5 chromosomes in G1. How many chromosomes will the cell have after it has completed the S phase?5101520
23A cell with 46 chromosomes in the G1 phase undergoes MITOSIS A cell with 46 chromosomes in the G1 phase undergoes MITOSIS. Which of these statements is true?4 daughter cells will be created and each daughter cell will have 23 chromosomes.2 daughter cells will be created and each daughter cell will have 46 chromosomes.4 daughter cells will be created and each daughter cell will have 46 chromosomes.2 daughter cells will be created and each daughter cell will have 23 chromosomes.

26Each chromosome consists of 2 _____. cellschromatidsdaughter cellsCentrioles
27The process of mitosis ensures that: each new cell is genetically different from its parenteach new cell receives the proper number of chromosomescells will divide at the appropriate timeDNA is replicated without errors
28During which phase of mitosis does the chromatin begin to condense to form the chromosomes? anaphasemetaphaseinterphaseprophase
29Which of the following phases of mitosis is not matched with one of the activities that occur during that phase:prophase: chromosomes replicate (copy)telophase: cytokinesis beginsmetaphase: chromosomes line up in the center of the cellanaphase: chromatids separate
30Which of the following describes cancer? Group of cells that grow and divideTumors that are present in vital organsCells that divide uncontrollablyDiscolored cells that are infected with bacteria
32In which stage do the spindle fibers align the sister chromatids along the center of the cell?
33In which stage are sister chromatids pulled to apart by the spindle fibers?
34In which stage does chromatin condense into chromosomes?
35The pinching off of the cell membrane that creates two daughter cells is called InterphaseAnaphaseCytokinesisdifferentiation
36Which of these cells in the human body, when mature, do not divide? LiverSkinNerveBlood
37genetically modified organism stem cell organism In 1994 a new tomato variety that ripens slowly was developed in the laboratory. This new variety of tomato contains a section of DNA not found in the tomato from which it was developed. This is an example of a(n)invasive speciesdifferentiated cellgenetically modified organismstem cell organism
38True or False. Stem cells typically give rise to the type of cell the correlates to the tissue in which they reside. (For example, a stem cell located in the bone marrow will differentiate into any number of different blood cells.)TRUE
