The binding of specific proteins on regulatory DNA sequences can be studied by means of:
Correct answer: D. X-rays crystallography
- A. Ultra centrifugation
- B. Electron microscope
- C. Light microscope
- D. X-rays crystallography
Explanation
X-rays crystallography is a technique which is used to study the binding of proteins on regulatory DNA sequences. In this technique, X-rays 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.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
