The answer is; electron microscope
This microscope has the highest resolution than the other hence able to view smaller molecules. The reason for its high resolution is because it uses a beam of electrons to view its specimen. A beam of electrons has a shorter wavelength (in order of 1000s of magnitude) compared to visible light. Therefore, this microscope is able to view the structure of DNA and proteins.
