Question:

You must have read about cells and DNA in your science books. Discuss Richard Ebright’s work in the light of what you have studied. If you get an opportunity to work like Richard Ebright on projects and experiments, which field would you like to work on and why?

Answer:

Ebrights’ work is directly related to Biology. Discovery of cell’s structure has helped scientific community to understand the way any organism functions and grows. This has helped scientists to discover how disease causing organisms attack us and grow inside our body. This must have given them idea to counter a particular disease . DNA fingerprinting is helping police to pinpoint the real culprit. This was not possible when DNA was discovered. Monarch butterflies present an amazing example of a tiny creature migrating thousands of miles from North America to the rainforest of Amazon. Some day we can be in a position to develop as sturdy and reliable navigation system as that of the Monarch butterflies. It I get an opportunity to work like ebright, I would like to work on the secrets behind the formation of this universe.
