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 |
