Biology Interactive Tutorials

Ed for All 1100. Introductory BiologyThis course features lectures by Professor Graham Walker, a Howard Hughes Medical Institute (HHMI) professor and director of the HHMI Education group at MIT, and Professor Sallie W. Chisholm, Lee and Geraldine Martin Professor of Environmental Studies and co-director of the MIT Earth Systems Initiative. The course covers the fundamental principles of biochemistry, genetics, molecular biology, and cell biology. Biological function at the molecular level is particularly emphasized and covers the structure and regulation of genes, as well as, the structure and synthesis of proteins, how these molecules are integrated into cells, and how these cells are integrated into multicellular systems and organisms. 1110. 1120. 1200. 1650. 1850. 2110.

Top 10 Amazing Biology Videos | Wired Science Cyborgs, stem cells, glowing mice, and hilarious music videos are great reasons to be excited about biology. Here are some of our favorite clips from the life sciences. 10. Immune Cell Chasing a BacteriumIt may look like the predecessor to Pac Man, but this vintage clip shows a neutrophil wending its way through a crowd of red blood cells to destroy its bacterial nemesis. 9. 8. 7. 6. 5. 4. 3. 2. 1. Last week, regenerative medicine researchers announced that they have grown a new windpipe for a woman who was crippled by tuberculosis. See Also:

Cell Size and Scale Some cells are visible to the unaided eye The smallest objects that the unaided human eye can see are about 0.1 mm long. That means that under the right conditions, you might be able to see an ameoba proteus, a human egg, and a paramecium without using magnification. A magnifying glass can help you to see them more clearly, but they will still look tiny. Smaller cells are easily visible under a light microscope. To see anything smaller than 500 nm, you will need an electron microscope. Adenine The label on the nucleotide is not quite accurate. How can an X chromosome be nearly as big as the head of the sperm cell? No, this isn't a mistake. The X chromosome is shown here in a condensed state, as it would appear in a cell that's going through mitosis. A chromosome is made up of genetic material (one long piece of DNA) wrapped around structural support proteins (histones). Carbon The size of the carbon atom is based on its van der Waals radius.

Bioman Biology: The Fun Place to Learn Biology! Nedeljnik Vreme Cellular Respiration Demo using Gummy Bears - Exciting!! This is a very simple demonstration that makes an impact. It illustrates energy release that occurs quickly. In the demonstration, Mr. Carter (the other science teacher at my school) visually reinforces the necessity of cellular metabolism’s small-step oxidation of glucose instead of releasing it all at once. The materials you will need for this demonstration are as follows: Approximately 1 tablespoon of Potassium ChlorateLarge test tubeGummy bear (or any other gummy animal)Fume hood (or any system to allow for the fumes to escape without engulfing the room)Eye protection (Lab Goggles, etc) The solid should be heated until it melts, and then the gummy bear can be dropped in. The products of the reaction should be potassium chloride (white deposit near the mouth of the test tube) as well as varying amounts of soot or charred gummy bear if not all of it is used up in the reaction. This kind of “all at once” release of energy would be catastrophic in a living organism.

The Biology Project HHMI BioInteractive - Virtual Labs BioInteractive’s virtual labs have won several awards, including top honors in the Pirelli INTERNETional Award competition, which recognizes the best multimedia products designed to use the Internet to educate about science and technology. Designed in close consultation with educators and scientists, these virtual labs are fully interactive biomedical laboratory simulations and provide students with skills and techniques used in scientific research. BioInteractive’s series of virtual labs allows students to examine heart patients, analyze DNA sequences, probe the nervous system of a leech, use human antibodies to diagnose disease, and measure physical traits of stickleback fish and anole lizards to examine key concepts in evolution. The labs can be accessed by clicking the icons on the right-hand side of the page.
