Terminology Needed for Mitosis:   1. mitosis - process by which a parent cell reproduces two identical daughter cells each  identical to the parent cell.   2. diploid (2N) - a cell that has two of each type of chromosome.   3. haploid (N) - a cell that has only one of each type of chromosome.    4. chromosomes - structures composed of DNA and protein that contain the genetic  information.   5. gene - a portion of a chromosome that contains a unit of heredity 6. homologous chromosomes - a similar pair of chromosomes that carry genes for the  same traits, each of which was inherited from a single parent; the homologous

Unformatted text preview: chromosomes must be copied before mitosis can proceed. Humans have 23 pairs of homologous chromosomes. 7. sister chromatids - two identical copies of an original homologous chromosome produced after the DNA replicates. 8. cytokinesis - the division of the cytoplasm that follows mitosis, to form the two new cells. 9. centromere - an area where the sister chromatids are held together. 10. mitotic spindle - microtubule structure that directs chromosome movement during cell division. 11. centriole - an organelle that possible organizes the mitotic spindle during mitosis....
