Ch. 11 Vocab

Front 1

spindle

Back 1

thin fiber structure that forms between the two poles or centrioles during prophase and shortens during anaphase, pulling the sister chromatids apart

Front 2

centromere

Back 2

cell structure that joins two sister chromatids of a chromosome

Front 3

telophase

Back 3

final stage of mitosis during which the two daughter cells become separated

Front 4

centriole

Back 4

pair of cylindrical structures composed of microtubles that duplicate during interphase and move to opposite ends of the cell during prophase; found in animal cells but seldom in plants cells

Front 5

sister chromatid

Back 5

identical halves of the duplicated parent chromosomes formed before the onset of cell divison; these exact copies are joined are the centromere

Front 6

cell cycle

Back 6

continuous sequence of growth (interphase) and divison (mitosis) of a cell, which is controlled by key enzymes

Front 7

gene

Back 7

a segment of DNA located on the chromosome; directsthe protiens production that controls the cell cycle

Front 8

chromosome

Back 8

cell structure that carries that genetic material

Front 9

interphase

Back 9

growth period of a cell during which chromosomes are duplicated

Front 10

cancer

Back 10

uncontrolled cell divison and death caused by the interactions between environmental factors and changes in the production of enzymes involved in the cell cycle

Front 11

mitosis

Back 11

cell divison during which chromosomes are equally disturbed to the two identical daugther cells that are formed; results in growth

Front 12

anaphase

Back 12

stage of mitosis during which the centromeres split and sister chromatids are pulled apart to opposite poles

Front 13

prophase

Back 13

1st phase of mitosis during which chromatin coils to form visible chromosomes

Front 14

metaphase

Back 14

second stage of mitosis in which chromosomes move to the equator of the spindle and chromatids are wach attached bye centromeres to a separate spindle fiber
