Mit lecture Transcript - Lecture 1/nAs I'm going to argue repeatedly today, biology has become a science over the last 50 years. And, as a consequence, we can talk about some basic principles. We can talk about some laws and then begin to apply them to very interesting biological problems. And so our general strategy this semester, as it has been in the past, is to spend roughly the first half of...

Video Lectures - Lecture 5/nTopics covered: /nBiochemistry 4/nInstructor: /nProf. Robert A. Weinberg/nTranscript - Lecture 5/nGood morning, class./nI just wanted to spend the first couple minutes clearing up three issues. None is a major conceptual issue, but we like to focus on details and get them right, get them correct here as well. Firstly, I misdrew a reaction last time that described why ...

Weinberg/nTranscript - Lecture 32/nSo we're shifting gears today. We're going to talk about molecular evolution, i.e., how do we understand how species evolve, how do we understand a lot about ourselves, how human evolution is taking place ov...

Today we're going to get into some stuff where we're kind of peering way back in evolution about how life first learned to make energy. But before we do that I just want to finish up talking a little bit more about enz...

Biology > Introductory Biology/n * Email this page/nVideo Lectures - Lecture 5/nTopics covered: /nBiochemistry IV/nInstructor: /nProf. Graham Walker/nTranscript - Lecture 5/nI've emphasized in the first lecture, you know, that there's a lot of stuff that happens just in your ordinary life. I saw two examples of this. Yesterday's Boston Globe, just on the front page there was a discovery about...

Biology > Introductory Biology/n * Email this page/nVideo Lectures - Lecture 11/nTopics covered: /nMolecular Biology III/nInstructor: /nProf. Graham Walker/nTranscript - Lecture 11/nSo just trying to remind you that the replication fork looks something like this where 5 prime to 3 prime and 5 prime to 3 prime. This is what's known as the leading strand because DNA, the synthesis of the new st...
