Question

Structure of RNA can be studied by

• A. Feulgen
• B. Toluene blue
• C. X-ray crystallography
• D. Chromatography

Answer 1

The correct option is C X-ray crystallography

X-ray crystallography is mostly used to study the structure of the crystal. The X-rays are incident on the crystal which is diffracted by the particles at different angles and intensity. By measuring the angles and intensities of these diffracted beams, a crystallographer can produce a three-dimensional picture of the density of electrons within the crystal. The technique can also depict the structure of RNA.

So, the correct answer is option C.
