    Gene Machine: The Lac Operon
    phet.colorado.edu/en/simulatio...
    In this video Paul Andersen describes the elements of an operon. The promoter allows the RNA polymerase to transcribe the required genes. The operator and repressor regulate the expression of the genes by blocking the RNA polymerase. The genes for a specific task are all located in sequence so that they can all be transcribed at once. He starts be describing how the lac operon can be initiated to break down lactose. He then explains how the trp operon can be activated to create tryptophan. He ends with a simulation of the lac operon.

    This has been more helpful than any lecture or book for me. As a visual learner, some subjects in biology taught mostly from the text book with the occasional image, has left me with a lack of understanding, only trying to do rote memorization for passing a test instead of understanding the concepts well. The combination of professor presence with simple and effective graphics has been extremely helpful. Thank you.

    Inducer process. It's called an inducer because lac induces the operon. (Process reduces lac in the end).
    Vs.
    Repressor process. It's called a repressor because it represses the operon in the presence tryptophan. (Process creates trp in the beginning)
