You have generated strains of Drosophila melanogaster that are expected to show interesting developmental phenotypes such as misplaced organs in the adult fly. However, some of these phenotypes are not readily seen with light microscopy. You therefore fix each mutant fly, dry it, coat it with a thin layer of gold, and place the entire fly into an electron microscope for viewing. What type of microscope are you using? Write down SEM or TEM as your answer.
