Question

________ a complex of DNA and protein housed in the nucleus of the cell. _______ the stage of mitosis where sister chromatids separate, moving to opposite poles. _______ refers to the division of the cytoplasm and associated organelles. _______ the last stage of the mitotic process where spindle fibers dissipate. _______ preparatory event to mitosis where DNA replicates. _______ refers to division of the nuclear material. _______ the genetic material housed in the chromosomes. _______ the entire whereby cells reproduce themselves (two words). _______ the stage of mitosis chromatid pairs align at the cell equatorial plane. _______ the first stage of mitosis where chromosomes become observable. cytoplasmic organelles that help produce spindle fibers. _______ attachment site of spindle fibers on the chromatids. _______process whereby DNA reproduces itself.^1

Explanation / Answer

Chromatin is a complex of DNA and protein housed in the nucleus of the cells. The responsible protein is histone proteins and the structural unit is called a nucleosome. Anaphase is the stage of mitosis where sister chromatids separate, and become individual chromosomes. Then move to the opposite poles. Anaphase is the third stage of mitosis. Cytoplasmic division or Cytokinesis refers to the division of cytoplasm and associated organelles. Telophase is the last stage of mitotic process where spindle fibers dissipate. Preparatory phase or G2 phase is the preparatory event before mitosis where DNA replicates. Mitosis or cell division refers to the division of nuclear material.
