Activation Energy and Enzymes TITLE: Activation Energy and EnzymesSOURCE: Freeman, S, Biological Science, Second Edition, Pearson Prentice Hall, Inc.© 2006 Pearson Prentice Hall, Inc.KEYWORDS: Activation energy, enzymes, exergonic reactions, ATP, activation energy, catalysts, lock-and-key model, induced-fit model New Genetic Twist: 4-Stranded DNA Lurks in Human Cells Sixty years after scientists described the chemical code of life — an interweaving double helix called DNA — researchers have found four-stranded DNA is also lurking in human cells. The odd structures are called G-quadruplexes because they form in regions of deoxyribonucleic acid (DNA) that are full of guanine, one of the DNA molecule's four building blocks, with the others being adenine, cytosine, thymine. The structure comprises four guanines held together by a type of hydrogen bonding to form a sort of squarelike shape. (The DNA molecule is itself a double strand held together by these building blocks and wrapped together like a helix.) The new visualization of the G-quadruplex is detailed this week in the journal Nature Chemistry. "I think this paper is important in showing directly the existence of this structure in vivo in the human genome, but it is not completely unexpected," said Hans-Joachim Lipps, of the University of Witten in Germany, who was not involved in the study.
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 Tree of Life Web Project The Tree of Life Web Project (ToL) is a collaborative effort of biologists and nature enthusiasts from around the world. On more than 10,000 World Wide Web pages, the project provides information about biodiversity, the characteristics of different groups of organisms, and their evolutionary history (phylogeny). Each page contains information about a particular group, e.g., salamanders, segmented worms, phlox flowers, tyrannosaurs, euglenids, Heliconius butterflies, club fungi, or the vampire squid. ToL pages are linked one to another hierarchically, in the form of the evolutionary tree of life.
Team:Freiburg/Project/Golden On this page, we introduce the Golden Gate Standard to the Registry of Standard Biological parts. We explain in detail, how Golden Gate Cloning works and how it can be made compatible with existing standards. Moreover, we provide step-by-step protocols for using this new standard.

The twisting tale of DNA - Judith Hauck Deoxyribonucleic acid, or DNA, is a nucleic acid containing the genetic instructions used in the development and functioning of all known living organisms (with the exception of RNA viruses). which contains the biological instructions that make each species unique, along with the instructions it contains, is passed from adult organisms to their offspring during reproduction. National Human Genome Research Institute began as the National Center for Human Genome Research (NCHGR), which was established in 1989 to carry out the role of the National Institutes of Health (NIH) in the International Human Genome Project (HGP). The HGP was developed in collaboration with the United States Department of Energy and begun in 1990 to map the human genome.
Interactive Ear tool showing how the ear works by Amplifon The ear is the organ which controls hearing and balance, allowing us to understand our surroundings and position ourselves correctly. It is split into three parts: outer, middle and inner. This guide will take you through each part of the ear in turn, answering those essential questions – what are the parts, what do they do, and how? Pinna Unseen Life on Earth: An Introduction to Microbiology 1. The Microbial Universe The world of microorganisms is a dynamic one, and all other life forms depend on microbial metabolic activity. Recent genetic research has uncovered only about one percent of the microbes that remain to be discovered. 2. The Unity of Living Systems All cellular organisms — prokaryotic and eukaryotic — share basic chemical similarities. Out of these similarities, however, emerge diverse patterns of cell assembly.
Biology Animations Carnegie Mellon's Office of Technology for Education and Department of Biological Sciences create multimedia materials for teaching and learning Biology. After an analysis of a number of Biology courses was performed to identify when and how shared concepts where taught, a team of biologists, media programmers, and learning experts came together to create animations designed to improve understanding of some of the main concepts taught in Modern Biology and Biochemistry.
