Match the form of microscopy to its description: Narrow wavelength light shines down on specimen and labeled antibodies, dyes, or fluorescent proteins glow: - Transmission electron microscopy Electrons pass through thin section of specimen and membranes and organelles are visualized: - Scanning electron microscopy White light: - Brightfield microscopy Broad wavelength light passes through specimen and dyes and/or filters reveal certain structures: - Fluorescence microscopy Electrons bounce off metal-coated specimen and surface features are revealed: - Scanning electron microscopy

When using a fluorescent microscope, the specimen you are observing acts as a light source. Green fluorescent protein (GFP) is commonly used in fluorescence microscopy, as shown in the image. In addition, our S. pombe yeast produces a DNA repair protein called Rad22 that has been tagged with GFP. Why will Rad22 appear green? We will add green dye to the yeast before viewing the cells on the fluorescence microscope. All DNA proteins are naturally green in color. The gene sequence for GFP has been inserted in the yeast genome, located immediately after the Rad22 sequence. Just before viewing the yeast on the fluorescence microscope, green proteins will be injected into the yeast. They will attach to the Rad22 proteins.
