This is what's known as the leading strand because DNA, the synthesis of the new st...

Biology > Introductory Biology/n * Email this page/nVideo Lectures - Lecture 12/nTopics covered: /nMolecular Biology IV/nInstructor: /nProf. Graham Walker/nTranscript - Lecture 12/nBy the time that Watson and Crick figured out the structure of DNA, you know, it was sort of obvious that since the two strands were complimentary you could see how it replicated. And they also could see that someh...

Video Lectures - Lecture 10/nTopics covered: /nMolecular Biology 1/nInstructor: /nProf. Eric Lander/n /nTranscript - Lecture 10/nGood morning. Yeah. All right. Good./nSomething to counteract the rainy days we have here./nAll right. Today we're going to make a very important transition. The transition goes back to this picture./nOf course, what we want to do is understand biological function by t...

Video Lectures - Lecture 4/nTopics covered: /nBiochemistry 3/nInstructor: /nProf. Robert A. Weinberg/nTranscript - Lecture 4/nAmong the issues that some people asked that should be discussed in greater detail should be the structure of proteins. I'll touch on it very briefly this morning, different kinds of bonding, tertiary and quaternary structure, condensation or dehydration reactions. And, i...

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 ...

Video Lectures - Lecture 8/nTopics covered: /nGenetics 3/nInstructor: /nProf. Eric Lander/nTranscript - Lecture 8/nLet's dive in today and look at how geneticists use genetics. I've told you up until now about some of the history of genetics and how it gave rise to our understandings about genetic transmission in traits, about genetic mapping, linkage analysis, how all this helped confirm the Ch...

Video Lectures - Lecture 6/nTopics covered: /nGenetics 1/nInstructor: /nProf. Eric Lander/nTranscript - Lecture 6/nI am the other half of the teaching team for 7.01. You've already gotten to meet my good colleague Bob Weinberg. My name is Eric Lander. And Bob and I are both faculty here in the Biology Department. In fact, we're both members over at the Whitehead Institute for Biomedical Research...

Video Lectures - Lecture 13/nTopics covered: /nGene Regulation/nInstructor: /nProf. Eric Lander/nTranscript - Lecture 13/nGood morning. Good morning./nSo, what I would like to do today is pick up on our basic theme of molecular biology. We've talked about DNA replication. The transcription of DNA into RNA, and the translation of RNA into protein. We discussed last time some of the variations bet...

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 12/nTopics covered: /nMolecular Biology 3/nInstructor: /nProf. Eric Lander/nTranscript - Lecture 12/nGood morning. Good morning./nSo, I'd like to pick up where we left off last time and just finish off translation and then step back and look at how this central dogma of DNA is replicated into DNA, is read into RNA, and is translated into protein./nOr, actually, as Franci...

Biology > Introductory Biology/n * Email this page/nVideo Lectures - Lecture 9/nTopics covered: /nMolecular Biology I/nInstructor: /nProf. Graham Walker/nTranscript - Lecture 9/nSo today we're going to continue our focus on DNA which I'm personally enthusiastic about at least in terms of being such a fascinating molecule. And I told you the story last time of how we actually came to understan...
