chap 10 & 11.4 VOCAB

process by which a cell divides into two daugher cells

part of eukaryotic cell divisions during which the cell nucleus divides

division of the cytoplasm during cell division

one of the two identical "sister" parts of a duplicated chromosome

area where the chromatids of a chromosome are attached

period of the cell cycle between cell divisions

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

second phase of mitosis, during which the chromosomes line up across the center of the cell

the third phase of mitosis, during which the chromosome pairs separate and move toward opposite poles

fourth and final phase of mitosis, during which the chromosomes begin to disperse into a tangle of dense material

series of events that cells go through as they grow and divide

one of two tiny structures located in the cytoplasm of animal cells near the nuclear envelope

fanlike microtubule structure that helps seperate the chromosomes during mitosis

one of a family of closely related proteins that regulate the cell cycle in eukaryotic cells

disorder in which some of the body's own cells lose the ability to control growth

term used to refer to chromosomes that each have a corresponding chromosome from the opposite sex-parent

term used to refer to a cell that contains both sets of homologous chromosomes

term used to refer to a cell that contains only a single set of chromosomes and therefore only a single set of genes

process by which the number of chromosomes per cell is cut in half through separation of homologous chromosomes in a diploid cell.

structure contianing 4 chromoatids that form during meiosis

process in which homologous chromosomes exchange portions of their chromatids during meiosis
