Now you can easily sample courses and find the ones that best scratch your intellectual itch. I bought this course to see what might be new. If my college biology class had been like this, I would certainly have taken a different route in Science. His creativity in adding a musical element to his lectures was a nice thoughtful touch for me. (Don't forget to check your junk email box!). Many organisms have the capacity for the kind of explosive population growth associated with bacteria. Priority Codes are on the back of the catalog, mail promotion, or within an advertisement. Surely, he has given this lecture many times for his 'day job' that he has the confidence to stand in front of his table and LECTURE - not READ his notes! Also look at intrinsically disordered proteins, which lack a fixed structure, permitting flexible interactions with other biomolecules. If they are not yet a customer, we will help them set up a new account so they can enjoy their course in their My Digital Library or via our free mobile apps. This experience is optimized for Internet Explorer version 10 and above. One of my big take-aways from the lecture course is the speed and precision of life structure and processes in the face of great complexity, which truly exemplifies how life is carefully balanced on a knife edge, with a potential for great disaster when the balance is lost. Cells go to great lengths to prevent mutations. Continuing the discussion of how new species arise, this lecture looks at sympatric speciation, which occurs in the absence of physical separation of populations.... How do biologists organize the enormous diversity of living things? How do curious non-scientists get an accessible introduction to these fascinating ideas? Professor Robert Sapolsky, however, really puts complex ideas into ways that are easy to understanding. We look at examples that illustrate key points.... For most of history, human population size was limited by the amount of resources available naturally in the environment. 4: Proteins-How Things Get Done in the Cell, 17: Charles Darwin and "The Origin of Species". Q: Oops! Protein-Synthesis Controls and Epigenetics. But numerous proteins have at least one region that is intrinsically disordered— a trait that allows them to bind to a wider variety of partners. On the other hand, when present in large quantities they can lead to Type 2 diabetes, and the wrong sugar markers on transfused blood cells can even kill us. Discover how to eat in a way that minimizes harm and efficiently fixes the inevitable damage from living. In this case, the dramatic change in thinking is directed inward—to the qualities that make us who we are. What a wonderful subject matter area. I have only gone through the first 6 lessons and I have learned a lot. Looking for The Great Courses Plus subscription service? What are priority codes? ands Please do not attempt to reset your password again in the next 30 minutes. Fill out the details on the next page. Then look at approaches to treating cancer, including use of agents that target rapidly dividing cells, whose side effects include hair loss. Survey the fats that obsess us in our diets and body shapes, notably triglycerides in their saturated and unsaturated forms. Investigate why water is so singularly suited to life. Trace the new technologies that have arisen from our understanding of recombination and repair of DNA, notably CRISPR, which permits precise alteration of gene sequences. He has been awarded fellowships from the Mary Flagler Cary Charitable Trust, the Alfred P. Sloan Foundation, and the John Simon Guggenheim Foundation. There is still plenty of “course meat” for further future reviews. He wants to make Biology more accessible to ordinary people also and that is what this course is. You have given me much to build-on and I would be very pleased to engage with any follow-on or related lecture course offered by Professor Ahern. This course has exceeded my expectations in many different ways. Study the ways that cells regulate enzyme activity by directing the synthesis and breakdown of biomolecules.
