Sample interview questions: What do you consider the most exciting recent development in the field of physics and why?

Sample answer:

One of the most exciting recent developments in physics is the emergence of topological materials. Topological materials are characterized by their topological invariants, which are numbers that describe the global properties of the material. These invariants are robust to changes in the material’s structure, and they can give rise to a variety of novel physical phenomena.

One of the most promising applications of topological materials is in the development of new quantum computing devices. Topological materials can be used to create Majorana fermions, which are particles that are their own antiparticles. Majorana fermions are immune to decoherence, which is one of the major challenges in building quantum computers.

Another exciting recent development in physics is the discovery of the Higgs boson. The Higgs boson is a fundamental particle that is responsible for giving other particles their mass. The discovery of… Read full answer

Sample interview questions: Have you used different expression systems like E. coli, yeast, or mammalian cells?

Sample answer:

• E. coli:

This is a prokaryotic expression system that is commonly used for expressing recombinant proteins. It is easy to grow and maintain, and it can be engineered to produce high levels of protein. However, E. coli is not able to perform post-translational modifications, such as glycosylation, which may be necessary for the proper function of some proteins.

• Yeast:

This is a eukaryotic expression system that is used for expressing proteins that require post-translational modifications. Yeast is more complex than E. coli, but it is still relatively easy to grow and maintain.

• Mammalian cells:

This is a eukaryotic expression system that is used for expressing proteins that are difficult to express in other systems. Mammalian cells are the most complex and expensive to grow and maintain, but they can produce proteins with the correct post-translational modifications.

Advantages of using different expression systems:

• By using different expression systems, you can take advantage of the unique features of each system to produce proteins that are properly folded, modified, and functional. Read full answer
