Answer #1

Option 3

Circular dichroism:--

->This is a form of a light spectroscopy method.

->It involves circularly polarized light.

->It measures the difference in absorbance of left and right circularly polarized light or unequal absorbtion of right and left handed polarized light.

->Circular dichroism in UV region(UV CD) is used to get the details of structure of secondary protein.
