Why I Do Science

When I look out my office window, I see two sets of nucleotide bases – guanine and cytosine. I don’t mention this as an admission of psychotic delirium. The building where I work just happens to have a DNA molecule emblazoned on its windows. Admittedly, it’s an odd workplace view, but in my case it fits.
I’m a molecular geneticist—genomics, gene expression, cloning, and the rest of that good stuff – and these little guys are some of the fundamentals of what I study. In many ways, my field is actually about the flow of information in genes; how a code is represented in that mother of all blueprints and gets read to construct something so detailed and nuanced as life. My area of interest is how the information in that chain is used and communicated. It almost always happens in the same way; DNA to RNA to protein. It’s as good a slogan as any, and from time to time we even get to call it dogma.
More important than this dogma, is the way my field appears to me to be so much bigger than the molecules I study. Molecular genetics represents some of the most exciting, profound, communal, and frightening aspects of the collective scientific endeavor. Its speed of advancement defies belief, and its effects on the social, cultural, political and economical issues of the day do not afford the luxury of ignorance.
That’s why I sit at my desk and look at that DNA; to remind myself of the larger importance of those molecules on my window not only to myself, but to everyone else. I see that I am a participant in a greater flow of information—from expert to layman, from creating the trenches where research happens to leading the tours that engage our local community.
I suppose this isn’t a fashionable reason to do science. Perhaps a more proper reason is to talk of the glory and honor of being “first” —the first to discover, to see, to understand. But in my mind, that privilege is severely limited to just one or a few. Frankly, I have my sights on something bigger: a privilege that can be shared with as many people as possible; to make science come alive.
Scientist to citizen to decisions made – wouldn’t that make a lovely dogma as well?
