These simulations and cases are based primarily on genetic and infectious disease with techniques such as: DNA electrophoresis, Southern blot, PCR, Multiplex PCR, Dot blot, ELISA, Western blot, 96-well PCR, protein electrophoresis. Case It! is collaborative BioQUEST project between the University of Wisconsin-River Falls and Michigan State University.
Dynamic National Archive
Welcome to the Dynamic National Archive (formerly the Timeline of American Women of Architecture). The mission of the Beverly Willis Architecture Foundation is to expand historical knowledge and cultural recognition of women’s contribution to American architecture of the 20th century. We define architecture broadly to include not only building design, but also landscape architecture, interior design, and urban planning. The Dynamic National Archive (DNA) is the first stage of an ongoing projec
Soil Change Guide - Procedures for Soil Survey and Resource Inventory
This Guide is designed for soil survey, vegetation, and ecological site or unit inventory work in order to help soil scientists and other inventory specialists collect interpretable data about soil change within the human time scale. This Guide describes a sampling system to measure dynamic soil properties for all major land uses (except urban lands where the land and soil have been significantly reshaped). The Guide includes instructions for project planning, field execution, and data analysis
NOP - Sustainable organic teaching lab
Sustainable development needs chemical research Research and innovation are preconditions for the transformation of economic and social processes in favor of a sustainable development. Chemistry, the science and practice of the transformation of matter, is of central importance. Everyone dealing with chemistry can contribute substantially to sustainable development and holds special responsibility. Already in education the links between reactions and substances with the consumption of energy and
Get This Bug Off Me!
It's a natural reaction to be frightened of some insects. Many insects have the ability to harm people, and many insects look very menacing. However, many large insects are not harmful at all. Because it would take several volumes to describe every insect, this publication is intended to distinguish several common insects and insect relatives in Kentucky that are or are not harmful.
A Manual of Online Molecular Biology Techniques
This is a collection of tried-and-true technique descriptions used in teaching postgraduate students in the Department of Molecular & Cell Biology at UCT.
SkyMath: Mathematics for a Blue Planet
SkyMath is a set of middle school mathematics modules incorporating weather data. The modules require teachers and students to acquire and use current environmental and real-time weather data in ways that embrace the dynamic and uncertain natures of these data, in order to promote the teaching and learning of significant mathematics, consistent with the standards set by the National Council of Teachers of Mathematics. The module includes 16 activities and can be incorporated as a replacement uni
Medical genetics involves the application of genetic principles in the practice of medicine. The material in this course encompasses diagnosis and treatment of genetic diseases (such as cancer genetics ), study of inheritance of diseases in families, mapping of disease genes to their chromosome locations, study of the molecular genetics and pathogenesis of inherited disorders, provision of genetic counseling for families, and investigations of methods for gene therapy. Unlike any other field, ge
The importance of the kidneys is most clearly demonstrated in the presence of pathophysiologic states. The kidneys play a central role in the maintenance of the internal milieu by balancing fluid, electrolytes, and hydrogen ions to provide optimal conditions for molecular, cellular, and body system function. They also serve as the major excretory organ for metabolic byproducts, drugs, and other organic substances. Finally, the kidneys are an important endocrine organ, producing vasoactive factor
Calculating Molecular Weight
The molecular weight is the mass of one mole of a substance. Usually, the units used for this are grams per mole. In this movie, we show how to calculate the molecular weight of a substance from the atomic weights given on the periodic table. On another page, we use the molecular weight to convert between the macroscopic scale (grams of a substance) and the microscopic scale (number of molecules of that substance).
Finding the Empirical Formula from a Molecular Formula
Elemental analysis is a useful qualitative analysis technique since it allows us to check if a sample is consistent with a given molecular formula. For instance, suppose we believe our sample is benzene (C6H6). We can compare the following:The empirical formula (CH) obtained from the molecular formula of benzene (C6H6); The empirical formula obtained from a elemental analysis of the sample. If the two empirical formulae do not agree, then the sample is not benzene. If the formulae agree, then ou
Finding Empirical Formula from an Elementary Analysis
On another page, we discuss how to obtain the empirical formula from a given molecular formula. Here, we consider how to obtain the empirical formula from an elemental analysis of a sample. Remember that comparing the empirical formula obtained from an elemental analysis with that from a molecular formula tells us if the sample is consistent with the molecular formula.
We are now ready to pull everything we know about reaction stoichiometry together, and answer the question: Given some initial amount of reactants, what should be present after a chemical reaction goes to completion? The procedure for answering this question is often called the "limiting reagent problem." You'll see why this name is appropriate in the following video.
You and a friend are hiking the Appalachian Trail when a storm comes through. You stop to eat, but find that all available firewood is too wet to start a fire. From your Chem 106 class, you remember that heat is given off by some chemical reactions; if you could mix two solutions together to produce an exothermic reaction, you might be able to cook the food you brought along for the hike. Luckily, being the dedicated chemist that you are, you never go anywhere without taking along a couple chemi
Mixed Reception Scenario
This activity is set in a research group that is developing an antivenom for spider bites. In the opening scene, Nelson Pogline, a talented graduate student, dies unexpectedly at a university reception. As a detective, you must use chemistry concepts to determine if this was murder and if so, solve the case. You can interview suspects using Quicktime movies, investigate the crime scene for clues with Quicktime Virtual Reality images, and analyze the evidence from the crime lab. This activity req
During the first kinetics lecture, we traced the efforts of atmospheric chemists to explain the depletion of ozone in the upper atmosphere. (The powerpoint slides have been posted on Blackboard for your review.) U2 spy planes gathered much of the initial data that linked ClO in the stratosphere to the ozone depletion. The data collected during these flights showed the concentrations of various chemical species in the stratosphere, but did not measure how fast the processes were occurring. To det
Product Formation and Percent Yield
In another tutorial, we considered the amount of reactant consumed by a chemical reaction. Here, we'll consider the amount of product formed by a reaction.
Reaction stoichiometry allows us to determine the amount of substance that is consumed or produced by a reaction. The following video considers the first part of this: how much of a reactant is consumed in a chemical reaction. Product formation is discussed elsewhere.

Step by Step Krebs cycle
These pages show the steps of the metabolic pathway called the Tricarboxylic Acid (TCA) cycle. Otherwise known as the citric acid cycle and the Krebs cycle. Data sheets, reaction diagrams and animations are provided for each step. Krebs cycle or the citric acid cycle or tricarboxylic acid cycle,occurs in mitochondria, is the common pathway to completely oxidize fuel molecules which mostly is acetyl CoA ,the product from the oxidative decarboxylation of pyruvate. It enters the cycle and passes
