Chapter 5: The Organization and Sequences of Cellular Genomes

Video 5.1  Mitosis in a Plant Cell

This sequence, recorded over about an hour, shows mitosis and cytokinesis in a Tradescantia stamen hair cell. Mitosis is the mechanism by which the duplicated genetic material in chromosomes is distributed to the two daughter cells. Note that each chromosome before anaphase has two chromatids; these are the duplicated strands of genetic material (DNA) complexed with proteins. (5.3 MB) [© Cytographics.]
