A. Yes, but not in detail. âMany scientists use electron, scanning tunneling and atomic force microscopes to view individual DNA molecules,â said Michael W. Davidson, curator of the National High Magnetic Field Laboratory at Florida State University.
A variety of different microscopes can be used to visualize the sub-cellular structures in a cell. They can be: a bright field microscope (simple in construction b â¦ ut not very accurate) A phase contrast microscope (gives a better idea of the three dimensional orientation of the sub-cellular structures) A fluorescent microscope (the most specific type of scope. This allows one to see very specific structures like the individual strands of actin that make up the cytoskeleton)
