Provides a brief overview of cell division, noting how the chromosomes line up in the center of the cell before being pulled apart to form two new cells. Mitosis (1:34) Follow the stages of mitosis, the systematic process that ensures that daughter cells formed when plant and animal cells divide get equal shares of DNA. Cell Differentiation (1:20) Follow as a single fertilized egg cell divides, differentiates, and assembles into the tissues and organs of a new organism. Cancer Cells (6:51) Cancer cells have lost their ability to stop reproducing. Scientists are working on ways to get the body's own immune system to fight cancer cells. How Cancer Cells Grow and Divide (1:37) Understand the role of oncogenes in uncontrolled cancerous growth and the journey of cancer cells from where they originate, into the circulatory system, and then on to other parts of the body.

How Cells Divide: Mitsosis and Meiosis Animal Cell Mitosis Animal Cell Meiosis Explore the step-by-step process by which an animal cell divides to make more cells. How Cancer Grows Follow the growth of a carcinoma from initial mutation to widespread metastasis. Cell Cams You may have seen time-lapse images of flowers opening and cells dividing. But how much really changes from one minute to the next? These webcams allow you to gauge those biological activities in "real time". How long does it take for a population of cancer cells growing in a dish to double? How long for a population of bacteria? Cancer Cell Cam This 24 hour series begins every midnight and shows cell division in a population of cultured cancer cells. Images are updated every 10 minutes throughout the day. Bacteria Cam This 6 hour series begins 4 times per day: midnight, 6AM, noon, and 6PM. A new image is loaded every minute. |
