Southern Blotting Southern blotting was named after Edward M. Southern who developed this procedure at Edinburgh University in the 1970s. To oversimplify‚ DNA molecules are transferred from an agarose gel onto a membrane. Southern blotting is designed to locate a particular sequence of DNA within a complex mixture. For example‚ Southern Blotting could be used to locate a particular gene within an entire genome. The amount of DNA needed for this technique is dependent on the size and specific activity

HYPERTENSION What is hypertension? Hypertension‚ also known as high blood pressure‚ is a common condition that occurs when the pressure of the blood in your artery walls is so high; it starts to complicate your health. Your blood pressure is based on how much the heart pumps and the amount of resistance to the blood flowing in the arteries. The harder it pumps‚ the more constricted the arteries are‚ the higher the blood pressure reads. High blood pressure can be in a person for years and go

in Baltimore‚ Maryland. His tombstone says that he was a master of light verse. Archibald MacLeish contests that‚ saying that his poetry is so much more than that. Sure‚ some of his poems are light and humorous‚ like The Cow: "The cow is of the bovine ilk; / One end is moo‚ the other‚ milk." Or The Fly: "God in his wisdom made the fly / And then forgot to tell us why." But there are other poems that show real insight that is true in the world‚ like the last two lines of Possessions Are Nine Points

In the environmental debate‚ some rank cattle up there with smokestacks and auto emissions. But Canadian researchers are discovering Mother Nature has developed her own mitigation strategy for bovine burps‚ flatulence‚ and excrement — and showing that grazing cattle has major environmental benefits. In 2000‚ concerns over cattle and greenhouse gases prompted Allan Iwaasa of Agriculture and Agri-Food Canada’s Swift Current research centre to launch a study to see what happens when cropland is seeded

Lungworm‚ a form of parasitic bronchitis‚ is an infection of the respiratory tract caused by the nematode‚ dictyocaulus viviparus. The species that is mainly affected by this disease is cattle‚ however‚ it can affect other species like deer. Within the bovine species‚ the dairy cattle are most likely to develop this disease. Similarly‚ the autumn-born beef cattle is just as prone to getting the disease. Least susceptible to the disease are the spring-born beef cattle. The animals become infected

Importance of Organic Foods The definition of organic agriculture is farming with the use of synthetic chemicals. After World War II‚ larger and increasingly automated farms‚ known as "factory farms‚" put the synthetic fertilizers‚ pesticides and herbicides developed in the 1920s into widespread use. They found that more crops could be produced mass produced. What they did not realize were the dangers of using these chemicals and the effects they would have on the environment and human health

Enzymes are found in all living cells as part of their protein constitution‚ which means that they are made of chains of amino acids bound together. These molecules provide energy for the organisms by catalyzing various biochemical reactions. Most of these chemical reactions would not take place in the conditions available if the enzymes were not a present. Therefore‚ we can say that being involved as catalysts is the main and most important role of an enzyme in any organism. Furthermore‚ many reactions
