Homework: Scrambled Sentences
#1 During prophase the chromatin condenses into chromosomes. #2 The major purpose of mitosis is growth and to replace worn out cells. #3 The phase in which the chromosomes are lined up at the center of the spindle is called metaphase. #4 The two daughter cells generated as a result of mitosis are genetically identical to each other. #5 A spindle is the structure responsible for moving the chromosomes during the process of mitosis. #6 Atthe endofinterphasecomes themitotic phase,which ismade upofmitosisand cytokinesis , leading to the formation of two daughter cells. #7 Interphase is composed of G1 phase (cell growth), followed by S phase (DNA synthesis), followed by G2 phase (cell growth). #8 Cells that aremeant to dividewill completeG2 phaseand entermitosis; while other types of cells that divide slowly or not at all may exit the G1 phase and enter a non-dividing state called G0. #9 The cell cycle is usually regulated by checkpoints, which are the factors that a cell considers when deciding whether or not to move forward through the cell cycle, and include both external cues (like molecular signals) and internal cues (like DNA damage). #10 Although we often talk about interphase and mitosis together, interphase is technically not part of mitosis. #11 A commonmisconceptionis thatDNAcopies itselfduring prophase,but this isnottrue; because in prophase, the DNA has already been copied while the cell was in interphase. #12 Because DNA is duplicated during interphase before the cell undergoes mitosis, the amount of DNA in the original parent cell and the daughter cells are exactly the same. #13 The cell spends most of its time in interphase; and mitosis typically occurs in about 2 hours.
