telophase {Ans: last phase of mitosis, chromosome are in two new cells and nuclear membranes start to reform}cell cycle {Ans: cell grows, prepares to divide, then divides to start growth process again; interphase + M phase}meiosis {Ans: type of cell division that creates gametes; creates four cells that are genetically unique}sister chromatids {Ans: a chromosome and its identical copy}metaphase {Ans: phase of mitosis in which chromosomes line up in the center of the cell}centromere {Ans: location where sister chromatids are attached}prophase {Ans: first phase of mitosis in which chromosomes become visible and nuclear membraine disappears}S phase {Ans: stage of interphase in which DNA is replicated}spindle {Ans: microtubule structure that separates chromosomes during mitosis}gamete {Ans: sex cell, sperm or egg}cancer {Ans: uncontrolled cell division}cell division {Ans: division of a parent cell into daughter cells}centriole {Ans: structure that helps to form the spindle}mitosis {Ans: division of the nucleus or chromosomes; creates two genetically identical cells}G1 phase {Ans: stage of interphase in which cell grows and performs its normal functions}crossing-over {Ans: process by which homologous chromosomes exchange pieces, resulting in greater genetic variety}G2 phase {Ans: stage
