a period between mitotic or meiotic divisions during which the cell grows, copies its DNA, and gains nutrients
in eukaryotic cells, a process of cell division that forms two new nuclei, each of which has the same number of chromosomes
threadlike structure within the nucleus containing the genetic information that is passed from one generation of cells to the next
A double membrane across the midline of a dividing plant cell between which the new cell wall forms during cytokenisis
the area of a cell membrane that pinches inward during animal cell mitosis eventually dividing the cell
a pair of chromosomes which contain similar genes arranged in the same order along the chromosome
the regrouping of genes in an offspring that results in a genetic makeup that is different from that of the parents
the production of offspring through meiosis and the fertilization of a sperm and an egg
genetic disorder in which an extra chromosome 21 is passed on. Also called trisomy 21
where females only have a single x chromosome instead of two. Also called monosomy 21
the first stage of mitosis or meiosis cell division, when the nuclear envelope breaks down and strands of chromatin form into chromosomes
the stage in mitosis or meiosis in which the duplicated chromosomes line up along the equator of the cell
the final stage of mitosis or meiosis, during which a nuclear membrane forms around sets of new chromosomes
