My Molecular Genetics professor made us DRAW a DNA replication fork with Okazaki fragments, and insisted that we be able to draw - molecule by molecule- every amino acid and an amino acid chain as well as a DNA or RNA strand. He figured if you could draw it you knew it. Bastard! He was my favorite teacher and an unabashed fan of Ronaldus Magnus Reagan; who asked the U.S.S.R. THREE times to let him emigrate as he was forbidden to teach or do research in the U.S.S.R.. He would introduce the story by saying (Ronald Reagan, who will ALWAYS be in my prayers, asked them three times to let me go. In a nation where being unemployed was forbidden, I was forbidden to work.)
I loved the guy because besides being an excellent teacher, he was a staunch anti-Communist (as only someone who experienced it can be), and a man of deep and profound religious conviction. I know a lot of FReepers seem to think all Biologists are atheist liberal conspirators out to deny God; but that is simply not the case. All my best teachers and mentors in Biology have been Christians.
This is due to cultural memories of JBS Haldane, Dawkins, and the (departed from FR for DarwinCentral) RightWingProfessor.
Cheers!
