  • Forest of large, towering trees. Caption: Well, redwood trees live for thousands of years,

    No organism lives forever. The length of time animals and humans live is influenced by their genes. Scientists have made astonishing discoveries concerning the role of genetics in determining life span, and this holds promise of extending the lives of animals and humans. Explains genetics, DNA, and genetic theories of aging. Illustrates the genetic processes behind cellular aging, and shows how genes affect life span. Discover the reasons why cells age and why a certain enzyme can effectively turn back the hands of our "biological clock."

    Four, 3D-printable models illustrating the major steps in bacterial cell division and the characteristics of exponential growth

    Most bacteria grown by fission, one cell dividing into two. When nutrients are abundant, this can result in exponential growth, with a large increase in the number of cells over a surprisingly short period of time. Bacterial cell division and the characteristics of exponential growth are illustrated with four, 3D printable models

  • A diagram shows six cell parts. Nucleus, Nuclear Membrane, Cytoplasm, Mitochondria, Vacuoles, and cell membrane.

    All living organisms on Earth contain cells which are the basic structural unit for all organisms. Cells are small compartments that hold the biological equipment necessary to keep an organism alive. They also have specific parts to make the cell work.

  • The Amoeba sisters present the heading, the cell cycle, with a D N A strand extending from left to right, below it.

    The cell cycle, or cell-division cycle, is the series of events that take place in a cell that cause it to divide into two daughter cells. In this episode, Pinky and Petunia discuss the steps of the cell cycle and what happens when the cell cycle doesn't work correctly. Part of "The Amoeba Sisters" series.

  • The Amoeba sisters present the heading, introduction to cells.

    All living things are made from one or more cells. A cell is the simplest unit of life, and they are responsible for keeping an organism alive and functioning. In this episode, Pinky and Petunia discuss the organelles of cells. Part of "The Amoeba Sisters" series.
