Extraction and Analysis of Plasmid DNA from E. coli Cells Introduction A plasmid is an extra-chromosomal element‚ often a circular DNA. Since a plasmid is by definition an extra-chromosomal element‚ it cannot make use of any origin of DNA replication in a chromosome (BP site). Meaning that DNA synthesis within a plasmid depends on having an origin of DNA synthesis of its own. Plasmids are often found in bacterial cells‚ in which they are used as transfer agents for transmitting various antibiotic

digestive system is one of the most crucial aspects of health‚ as your digestion takes the nutrients from your food and turns it into fuel that is usable by your body. We also don’t have four stomachs‚ like baby cows do‚ and we can’t expect to be able to digest something created specifically for baby cows - our digestive systems are too different. Our bodies stop producing lactase (the enzyme to break down lactose) as we grow into adults. BUT the Masai and Loetschental Swiss civilizations‚ who are free of

gets it nutrients from the insects and other small animals that it digests. Just like any other plant that you might see‚ the Venus flytrap does in fact grow from photosynthesis and gets its energy to do this from the insects that it digests. They also respond to their habitat and the environment around them‚ by using their tiny hairs on the opening of the plant to sense movement of animals and immediately close in order to digest the insect for the energy it provides. They also follow another characteristic

previous case law from which it was derived no longer binding or viable precedent. In 533 the Digest was written‚ and was a summary of the voluminous Code‚ as well as a guide for judges as to what precedent is to be enforced. This was relevant‚ as the Code didn’t go into case specifics as much as individual cases themselves did‚ and the Digest pointed judges to which cases could still be used as precedent. The digest also introduced some of Justinian’s personal laws as well‚ which required the Code to be

Post Workout The reason whey is so popular is the speed at which we digest it. Whey is digested quicker than any other protein source. This makes whey great for post workout because the amino acids quickly feed muscle tissue‚ supporting immediate muscle growth and repair. Whey is the number one ranking protein source on the BV (biological value) chart‚ too. BV rates proteins by their efficiency for generating new body tissue‚ such as muscle tissue. Whey isolate‚ the most pure form of whey protein

digestion of milk fats by pancreatic lipase and the digestion of proteins by pepsin and trypsin By Jenny Lam Abstract The purpose of this project was to determine how pancreatic lipase and bile salts digest fats to fatty acids and glycerol and how pepsin and tryspin digest to polypeptides. Litmus solution (pH indicator) was used for the fats to indicate the occurrence of the digestion of fats in experiment A. Egg whites was used as the substrate for the enzymes in experiment B. The pH

Seventy-four percent of those individuals were reported to own more than one firearm (Congressional Digest 2).” By 2000‚ the total number of firearms that people in United States have increased to about 259 million (Congressional Digest 2). By 2009‚ the total amount of firearms that U.S people had was about 310 million (Congressional Digest 4). So‚ did increase in total number of firearms increase crime rate? No. If we take a look at the reports that have been reported

Bread is made out of carbohydrates. In the digestive system‚ carbohydrates start the digestive process in the mouth. Salivary amylase is created by by three large salivary glands. This amylase breaks down starch and carbohydrates. However‚ since only a few people keep the food in their mouth long enough for the amylase to digest the

left side of the upper abdomen. The stomach receives food from the esophagus. As food reaches the end of the esophagus‚ it enters the stomach through a muscular valve called the lower esophageal sphincter. The stomach secretes acid and enzymes that digest food. The lining of the stomach secretes hydrochloric acids and enzymes that break down the food so that it can continue on its journey through the digestive system. As it secretes acid and enzymes‚ the stomach muscles contract in a process called
