Chromosome Number		Type of nuclear division that maintains the parental chromosome number for daughter cells
Chromosome Number		A cells collection of DNA and all of the proteins assosiated with it
Germ Cell		One of two or more molecular forms of a enge that arise by mutation and code
Somatic Cell		Haploid cell, formed by meiotic cell division of a germ cell; required for sexual reproduction
Chromosome		Eukaryotic cells, DNA molecule. duplicated or not, with associated proteins
Egg (ovum)		From nuclear division, a splitting of the parent cell cytoplasm
Centriole		The fusion of a sperm nucleus with the nucleus of an egg, thus forming a zygote
Sexual Reproduction		Structure that gives rise to microtubules of cilia and flagella
Metaphase		At prophase I of meiosis. an interaction in which nonsiter chromatids of a pair of homologous chromosomes break at corresponding sites
Oocyte		All chromosomes in a given type of cell
Gene		Cancer cell of a lineage reproduction established for cancer research
Allele		Two-stage nuclear division process that halves the chromosome number of a parental germ cell nucleus
Telophase		Process of Cytoplasmic division in plant cells
Histone		Mature male gamete
Centromere		A reproductive or resting structure of one or a few cells, often walled or coated
Cell Cycle		Animal cell of a lineage set aside for sexual reproduction
Gamete		All Chromosomes in a given type of cell
Diploidy		Mature female gamete; an ovum
Interphase		Any reproductive mode by which offspring arise from a single parent and inherit the genes of that parent only
Crossing Over		When cell increase mass and doubles cytoplasm, also duplicates its DNA
Anaphase		Cell Cycle, interval between nuclear divisions when a cell increase mass
Clevage Furrow		Ringlike depression defining the cutting plane for a dividing animal cell
Cytoplasmic Division		Unit of information for a heritable trait, passed from parents to offspring
Nucleosome		A stage when one member of each pair of homologous chromosomes has arrived at a spindle pole
Sperm		Production of offspring be meiosis, gamete formation, an fertilization
Spore		Type of protein intimately associated with eukaryotic DNA
Fertilization		A stretch of eukaryotic DNA looped twice around a spoll of histone molecules
Asexual Reproduction		Type of immature egg
Meiosis		When sister chromatids of each chromosome move to opposite spindle poles
Chromatin		Of Meiosis I, stage when all pairs of homologous chromosomes have become positioned at the spindle equator
HeLa Cell		Constricted area of a chromosome which has attachment sites for spindle microtubules
Mitosis		Pressence of two of each type of chromosome
Cell Plate Formation		Any body cell that is not a germ cell
