So for the past few months I’ve been frantically studying for not the GRE, but for my preliminary exams for my PhD. I will therefore be adding blogs that answer potential questions from my prelims in addition to GRE questions. This should be fun for all! My advisors have been giving me “hints” (i.e. “know [...]

Let’s do an easy one, shall we? Ok! Here’s the question: The cDNA fragment that includes the ricin gene is 5.7 kilobases. If the entire fragment codes for the ricen polypeptide,the approximate number of amino acids in the poly peptide would be: (enter some weird numbers with lots of zeros here). Well, once again the [...]

Well, I’m sitting at a conference at the moment, and have decided that it has been too long since I have indulged in the joy of biological teaching. Seriously! Stop laughing. Here’s the question I randomly chose for today: The rate at which a DNA fragment moves in an electrophoretic gel is primarily a function [...]

Could I come up with a more boring title? I don’t think so! But how in the world do you write something interesting about how DNA copies itself? Maybe “base pair porn!” That would totally work! I’m putting that now…hee for me! Anyhow, on to today’s question! When DNA replicates semi conservatively, which of the [...]
