DNA Structure - Contents page (Fabien) An Interactive Animated Nonlinear Tutorial by Eric MartzAdapted for using Jmol instead of Chime, by Angel Herráez Part of Biomodel website by Angel Herráez, Univ. de Alcalá (Spain) Disponible también en español. Também disponível em português. Auch verfügbar auf Deutsch. Disponible aussi en français. This version 4.3 works in any Java-compatible browser. If you prefer using Chime for molecular models, the page using it is still available, with equivalent content and functionality. This tutorial is designed to complement Biology or Biochemistry and Molecular Biology books, so it is not by itself a complete introduction to DNA structure. Before proceeding, check that your browser has Java installed and can use the Jmol software: This tutorial is designed to complement an introduction to DNA, by providing tools for a self-directed exploration.

Cell Models For life all cells have basic needs. Cells have diverged in their structure and function to accommodate these survival requirements. Here are some KEY TERMS to help you think, explore and search for similarities and significant differences that have become the characteristics of eukaryote (animal, plant) and prokaryotic (bacteria) cells. Examples might be searching: eukaryote prokaryote reproduction or animal plant cell energy. Reproduction / cell division Energy trapping, storage and consumption Form / shape / structure Cell specialization Compartmentalization of cell functions Communication within and beyond the cell Cell / organism survival Virtual Fetal Pig Dissection | Whitman College (philippe) Welcome to the Whitman College Biology Department's Virtual Pig Dissection (VPD)! This site is designed as a supplement to laboratory dissections exploring introductory mammalian anatomy and physiology — it is basic and many details have been omitted for clarity. We hope that it is suitable for AP Biology students or for students of introductory anatomy and physiology at the college level. We have revised this site to improve the learning experience and accessibility. Within this site, you can navigate to any chapter from the links at the left.
Pascaline On your bike: how muscles respond to exercise We all know that exercise makes us fitter and healthier – but what changes take place in our cells to make this happen? Next time you are working out in the gym, or pounding the streets running or jogging, ponder this: the idea of ‘muscle memory’ – that today’s exercise has effects on our muscles years from now – has never been demonstrated scientifically. Does it really exist, and if so, how does it work? These are some of the questions we hope to answer in our on-going research, which aims to pin down the changes that occur in muscles when we exercise, and how our muscles ‘know’ to respond differently to, say, endurance training as opposed to strength training. Helping us to investigate these questions is a large team of volunteers. We assess the fitness of our volunteers before and after participation in the studies by measuring their maximal oxygen uptake. Of course, we already know that regular exercise produces health benefits. Building mitochondria Epigenetic factors Acknowledgement
problème obésité : Persuasive Games -Fatworld (laura philippe) Fatworld is a game about the politics of nutrition. It explores the relationships between obesity, nutrition, and socioeconomics in the contemporary U.S. Fit or Fat? In the last two decades, obesity has soared in the United States. Public and private organizations have mounted ongoing efforts to change Americans’ behavior toward nutrition and exercise. More importantly, these efforts assume that our obesity crisis is caused solely by lack of self-control: if only everyone would choose to eat right and exercise, the problem would go away. Fatworld is a videogame about the politics of nutrition. Existing approaches to nutrition advocacy fail to communicate the aggregate effect of everyday health practices. You can choose starting weights and health conditions, including predispositions towards ailments like diabetes, heart disease, or food allergies. Interested in politics?
A Serious Game on Biodiversity in Wheat Farming | KTM Advance April 28, 2014 A Serious Game on Biodiversity in Wheat Farming Lu, the leading French cookie manufacturer, further confirmed its desire to minimize the company’s impact on the environment by creating LU Harmony. This new wheat network, created in partnership with French farmers, favors biodiversity and guarantees quality wheat farming. In 2010, KTM Advance created a serious game to allow young players to learn about the sustainable development LU defends and dive into the wheat field ecosystem. They also learn how to grow quality wheat and maintain local biodiversity. The “Harmonyculteurs,” or “Harmony Farmers,” deals with complex information in a fun and accessible way.
Serious Games To Learn About A Biologically Diverse Ecosystem Serious Games addressing biodiversity, ecosystems, and natural selection Related posts: TyrAnt, by Preloaded, is one of the three Serious Games nominated in 2014 for the Games for Change Best Gameplay award category. Preloaded has been working with Amplify to produce a series of games to be sold to schools across the United States, designed for the Amplify Tablet and a variety of other platforms including iOS. As part of their focus on Science they have developed TyrAnt, a light, Real-Time Strategy (RTS) game where the player seeks to protect and grow a colony of ants. Serious Game to experience how ants reproduce within a delicate and biologically diverse ecosystem Developed for Android and iOS platforms, the game allows players to discover the hidden world of ants through intuitive touchscreen controls and strategic mechanics. The lifeblood of the colony is fresh green leaves - the resource the player must gather in order to grow the colony and trigger the flying ant’s nuptial flight.
Endurance exercise 'interferes with heart rhythm' Pascaline Athletes beware - endurance training may make it more likely that you will need a pacemaker, scientists believe. A British Heart Foundation team found exercise in mice triggers molecular changes in the part of the heart that generates its natural beating rhythm. This may explain why elite athletes have low resting heart rates and more risk of heart rhythm disturbances, they told Nature Communications. However, the benefits of exercising still outweigh any risks, experts say. Super-fit Endurance athletes are generally very fit. Yet, paradoxically, they are more likely to have heart rhythm disturbances, known as arrhythmias, especially as they get older - although the risk is still small. Experts have suspected that this is because long-term training for extreme endurance events such as marathons and triathlons slows the heartbeat down. Cyclists Sir Chris Hoy and Miguel Indurain reportedly had resting heart rates of 30 and 28 beats per minute. How to exercise
