The size of DNA is way too small to be seen by a microscope. X-ray Crystallography can be used because it sends x-rays at a molecule and then the machine measures the pattern of the x-rays to construct a 3D image of the DNA molecule
Because DNA is not visible with a light microscope. In order to visualize DNA you need to use an electron microscope. The double helix was confirmed using X-Ray diffraction by the way.
DNA is too small to visually make out the structure; even the best modern light microscopes can't see that it's a double-helical shape. However, crystallizing it, bombarding it with x-rays, and looking at the diffraction let them get a better look.Specifically, the wavelength of visible light is too big to see it.Good on you, Rosalind Franklin. (And Watson and Crick too, I GUESS)

She was close to solve the 3D structure of the DNA molecule, she had even got the X ray diffraction pattern that was helped solve the structure by Watson and Crick.
You should use research and investigation to solve that problem.The scientist used research and investigation to perform her experiment. Research and investigation are the foundations of science.

it helped us see tiny cells
it helped us see tiny cells
Seeing things that are smaller than you can see with a magnifying glass.
To solve your problem
the meaning of everything
scientific
To solve specific problems
A medical scientist usually makes the medicines. They find a problem and then they study then solve it with medicine.
