MCQ

Question

Given below are two statements : Statement I : Dynamic light scattering principle can be used to determine the approximate size and dimension of a protein in solution. Statement II : Circular Dichroism spectroscopy can map protein-ligand interactions. In the light of the above statements, choose the correct answer from the options given below :

Options

Choose one · Correct answer highlighted

Explanation

Dynamic light scattering analyzes fluctuations in scattered light from Brownian motion to calculate hydrodynamic radius and approximate size of proteins in solution. Circular dichroism spectroscopy measures differential absorption of left and right circularly polarized light to assess secondary structure, not direct mapping of protein-ligand interactions.
