Binding of specific protein on regulatory DNA sequency can be studied by means of (a) ultra centrifugation (b) electron microscope (c) light microscope (d) Xrays crystallography
Option D Xrays crystallography is a technique which is used to study of binding protein on regulatory DNA sequence. In this technique, Xrays pass through a crystal of a substance and form a diffraction pattern. With the help of this technique, the arrangement of atoms in the molecular structure of enzymes, proteins, DNA, etc. can be studied. Wilkins, Watson and Crick used this technique to determine the molecular configuration of double helix of DNA.
