Directions. 1  Heat oven to 400Â° F. Pierce each sweet potato several times with the tines of a fork. 2  Place the sweet potatoes on a rimmed baking sheet lined with foil. 3  Bake until tender, about 45 minutes. 4  Make a slit in the top of each sweet potato.
Mitochondria under the microscope. Microscopes have been crucial for our understanding of mitochondrial structure and function. Mitochondria are visible under the light microscope although little detail can be seen.Transmission electron microscopy (left) shows the complex internal membrane structure of mitochondria, and electron tomography (right) gives a three-dimensional view.itochondria under the microscope.

In 1962 at the Rockefeller University, in New York, New York, Hans Ris and Walter Plaut, using the electron microscope, discovered DNA in chloroplasts. In 1963, at the Rockefeller University, in New York, New York, Margit Nass and Sylvan Nass discovered DNA in mitochondria.ithin each mitochondrion is the mitochondrial DNA (mtDNA), which is different from the DNA in the cell's nucleus (nDNA). Organisms inherit their mitochondria only from their mothers via egg cells (oocytes).
