The first strands of dna were observed through which microscope? tunneling microscopesimple microscopecompound light microscopeelectron microscope

Technically, X-ray crystallography, which is like an unfocused electron microscope, was first used to see DNA structure. Scientists today use more refined electron microscopes for researching DNA and its structure

Explanation:

The electron microscope is a kind of microscope that uses a beam of electrons to produce an image of the specimen. It is acceptable of important special magnifications and has a greater resolving power than a light microscope, providing it to see much smaller objects in precise detail.

the answer is c cumulus. cumulus clouds can be seen on a gray and rainy day, because cumulus clouds create thunderstorms. give me brainliest if right.
