Cell Division Vocab

Across

  1. chromosome pairs (one from each parent) that are similar in length, gene position, and centromere location. (homologouschromosomes)
  2. a distinct sequence of nucleotides forming part of a chromosome, the order of which determines the order of monomers in a polypeptide or nucleic acid molecule which a cell (or virus) may synthesize. (gene)
  3. The region of a chromosome to which the microtubules of the spindle attach ( via the kinetochore) during cell division. (centromere)
  4. An organelle near the nucleus of a cell which contains the centrioles (in animal cells) and from which the spindle fibers develop in cell division. (centrosome)
  5. a highly regulated membrane barrier that separates the nucleus from the cytoplasm in eukaryotic cells. It contains a large number of different proteins that have been implicated in chromatin organization and gene regulation. (nuclearenvelope)
  6. The resting phase between successive mitotic divisions of a cell, or between the first and second divisions of meiosis. (interphase)
  7. The first stage of cell division, before metaphase (prophase)

Down

  1. A type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth (mitosis)
  2. Either of the two cells formed when a cell undergoes cell division by mitosis . (daughtercell)
  3. A type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores. (meiosis)
  4. The material of which the chromosomes of organisms other than bacteria (i.e., eukaryotes) are composed. It consists of protein, RNA, and DNA. (chromatin)
  5. Each of the two threadlike strands into which a chromosome divides longitudinally during cell division (chromatid)
  6. Refers to the identical copies (chromatids) formed by the DNA replication of a chromosome, with both copies joined together by a common centromere. (sisterchromatid)
  7. A threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes. (chromosomes)
  8. The number and visual appearance of the chromosomes in the cell nuclei of an organism or species. (karyotype)
  9. A minute cylindrical organelle near the nucleus in animal cells, occurring in pairs and involved in the development of spindle fibers in cell division. (centrioles)
  10. a radiating array of microtubules associated with a centrosome in a dividing cell. (aster)
  11. Filaments that form the mitotic spindle in cell division, i.e. mitosis and meiosis. (spindlefibers)
  12. The second stage of cell division, between prophase and anaphase, during which the chromosomes become attached to the spindle fibers. (metaphase)
