Lecture 7b: From Genes to Proteins (Pt. 2)
This is the second episode in our two part series on transcription and translation, that is, how cells produce the proteins they use. Last time we talked about transcription, so we’ve already covered how we use cellular machinery to create edited mRNA transcripts. Today we’re going to be talking about what the cell does with those transcripts once it’s got them, how it goes from mRNA to protein. So let’s talk about translation on the Full Semester Biology Episode 7: From genes to protein...
Lecture 7a: From Genes to Proteins
Today we're going to be talking about the nucleus, and what happens there. We’re talking about how cells use their DNA to produce mRNA that will be translated into proteins. This episode takes us through a short history of genetic thought, transcription, and post-transcriptional modifications. So let’s talk about transcription on the Full Semester Biology Episode 7: From genes to protein Part 1. http://cytochemistry.net/_Media/nucleo3_med.jpeg Trascription image I was talking about during...
Lecture 6: A Tour of the Cell
Today we’re going to have a pretty long episode. I’m going to take you on a nice leisurely tour of the cell. You’ll learn all about the structures that make up cells, what they do, and how they interact. All organisms are made of cells, so we should talk about them! They're the simplest collection of matter that can live, it's the most basic form of life! Join me, for the full semester podcast, episode 6, a tour of the cell.
Lecture 4: Functional Chemistry
Today we’re going to finish up talking about carbon and start in on the properties of biological molecules. I know it can seem like I’m dragging on about chemistry and not getting to the biology here, but there are some subtleties in this episode that really make a big difference in the real world, like the concept of enantiomers and functional groups. I think you’ll really like this one, so stick with me!
Lecture 2: More introduction
Hey all, welcome back! Today we're going to be finishing up the introduction to biology by thinking about what science is as a concept, we'll go through some themes that permeate biological science, and we'll end with a description of a field experiment from a paper I read recently.

Paper 1: "Evolution and Tinkering"
This article is Franscois Jacob's 1977 article in the journal science titled "evolution and tinkering". In this article we explore a really foundational concept in Evolution, that of constraint. The author highlights the fact that constraint is not only biological, but it also applies to our thinking about how evolution works. He demonstrates this by showing how the action of an "engineer" doesn't apply very well to evolution, but rather that we should think of evolution as a "tinkerer"...
