In this regard, what microscope can be used to examine cells?
Two types of electron microscopy—transmission and scanning—are widely used to study cells. In principle, transmission electron microscopy is similar to the observation of stained cells with the bright-field light microscope.
Hereof, how do they know what DNA looks like?
Scientists have developed a new method of imaging the building blocks of life. It involves an electron microscope and a bed of nails. When we look at those now-iconic images of the double helix, the fuzzy X inside the fuzzy O, we're not seeing the DNA itself so much as we're seeing x-rays deflected from its atoms.
Under a microscope, the familiar double-helix molecule of DNA can be seen. Because it is so thin, DNA cannot be seen by the naked eye unless its strands are released from the nuclei of the cells and allowed to clump together.
