My notes and thoughts from Biology 111, for Monday, September 22, 2008. The entire series can be found here.
Before we get to the actual lecture, there’s something I need to address here.
While taking notes, it is often helpful and even necessary to draw little diagrams and pictures, many of which I reproduce in this series by digital means.
This is often simpler, neater, and more helpful than just scanning pages of notes from my notebook.
Until now, it’s really not made much of a difference, but in this lecture we begin drawing diagrams of cell structure, and while it’s not terribly difficult to do digitally, when drawing them in a notebook it is imperative for accuracy to understand the proper method for drawing a cell. It is a skill which requires a great deal of practice.
Chromosomes and various proteins for example, can be very complicated, and drawing them incorrectly can lead to gross misunderstandings and disaster for the student. To help prevent this, I’ve created a digital animation of the proper method for drawing a chromosome inside a prokaryotic cell. The method employed here can be extended and extrapolations to eukaryotic cell diagramming should not be difficult.
The method, along with this lecture, is below the fold.
