Questions & Answers

Q: What are the core themes of the course?

The core themes include studying life at a molecular level, understanding the cellular environment, and exploring complex processes carried out by macromolecular machines.

Q: How can understanding molecular features explain mechanisms of human disease and therapeutics?

By studying molecular features, such as the structure and function of ribosomes or the proteasome, we can understand how small molecule therapeutics target these biomolecules and potentially develop new treatments for diseases like cancer or coronary disease.

Q: Why is experimental design important in biochemistry?

Experimental design is critical to obtain reliable and meaningful data. Different techniques have inherent strengths and limitations, and scientists must carefully choose the appropriate methods and consider the cellular or physiological context for accurate interpretation.

Q: What are some challenges in studying cellular processes at a molecular level?

The complexity of cellular processes requires the use of multiple experimental methods. Additionally, the cellular environment is vastly different from the test tube, and researchers must carefully relate their data to the physiological context. The hypothesis is also a moving target, and new insights and uncertainties often arise.
