The dude teaching me biochem–who, by the way, has the most gorgeous flowing silver tendrils of hair–discovered the mechanism behind the Lac repressor. All of you milk drinkers out there, lift your glass to M. Lewis!
(In case of confusion, above picture is not of my professor, but I think he totally deserves a featured advertisement.)

Problem: that article does not help me at all to understand what the “lac repressor” is. Based on the picture I can only guess it is milk-related. But it could be hip-hop-related instead. (Based on M. Lewis’s gibberish, how could I know???)
By the way, I think your photos and illustrations add a lot of character, charm, and quirkiness to your blog in general, and I affirm that.
Whoa–so sorry for the delay. Megan, thank you so much for your comment–both helpful and sweet.
Yeah, I’m still trying to figure out how much I should be explaining…I now realize that the article is pretty vague and not that helpful. The lac repressor is more exciting because it’s something that pretty much every pre-med learns about as an example of gene regulation (what genes our body decides to turn on and off) in bio 101. Not terribly interesting to me otherwise but, yes, it is milk-related. Now I really wish it were hip-hop related…that would certainly excite me more.
I’m super flattered that you checked out the blog. Miss you!
