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.
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
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)

you call a scientist a scientist but there are different study's in science which are called different names i hope this helps.:)
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.

A scientist uses the information as a beginning for solving a problem.
Microscope manufacturer: Companies specialized in designing, producing, and selling microscopes and related equipment. Microbiologist: Scientists who study microorganisms using microscopes to identify, classify, and understand their structure and behavior. Histotechnologist: Professionals who prepare tissue samples for microscopic examination in medical laboratories. Quality control technician: Individuals responsible for inspecting products using microscopes to ensure they meet specific standards. Forensic scientist: Experts who analyze evidence such as hairs, fibers, and blood samples under microscopes to help solve crimes.
Microscopes help solve problems related to observing and studying extremely small or microscopic objects, such as cells, bacteria, and viruses. They also aid in identifying and diagnosing diseases, studying the structure of materials at the micro-level, and advancing scientific research in various fields.
