You need to look at cell under a microscope, proteins using X-Ray crystallography (for example), and DNA and RNA by various methods like gel electrophoresis or cell staining (see more about visualizing DNA here). Many experiments require scientists to manipulate DNA, RNA or proteins in small liquid volumes to do experiments to understand the sequence of these molecules, to ...

Every lab that I've ever worked in, I gave tons of tours - to my family, to other scientists, to kids and to the public! Seeing what a real lab looks like and understanding how things work is one of the ...
