Welcome to the Structural Biology MCQs with Answers. In this post, we have shared Structural Biology Online Test for different competitive exams. Find practice Structural Biology Practice Questions with answers in Biology Tests exams here. Each question offers a chance to enhance your knowledge regarding Structural Biology.

That’s the subdiscipline of molecular biology, biochemistry, and biophysics dealing with studies, in research, on the structure of biological macromolecules-most specifically, proteins and nucleic acids. It entails how they adopt their particular three-dimensional form or conformations and that such a structure is vital for their performance.

Of course, these macromolecules in their atomic structure would provide much info about their functions, the ways of action, and how they interact with other molecules. Some of the common techniques are X-ray crystallography, nuclear magnetic resonance spectroscopy, and cryo-electron microscopy.

In fields such as drug design, where molecular targets might be visualized and more precise therapies designed, structural biology plays very central roles. It is thus fundamental to the determination of biological macromolecules’ structure that underlies deciphering complex life processes on a molecular level-from the activity of enzymes to gene regulation.
