Common household items (chemicals) found in cells - Essay Example The amino acids in a protein determine how it folds into a three-dimensional shape; this structure is, in turn, responsible for the proteins function. Proteins carry out almost all the functions needed for cells to live. A change to the DNA in a gene can change a proteins amino acids, changing its shape and function: this can have a dramatic effect in the cell and on the organism as a whole. Major metabolic reactions by which the cell obtains and stores energy is in the form of ATP. This metabolic energy is then used to accomplish various tasks, including the synthesis of macromolecules and other cell constituents like carbohydrates, lipids, proteins, and nucleic acids. Researchers believe that RNA is a unique molecule and the earth is home to RNA-based organisms, which could find food, grow and reproduce and gradually switch to double-stranded DNA. Proteins cannot be made by RNA-based organisms, so they could live where main ingredients like sulphur, required for protein synthesis is absent. By extraction of DNA, the genome pattern of various species can be established. Scientists are rewriting the genetic code and using engineered bacteria making new proteins with new amino acids. Designing new proteins, looking for signs in metabolic activity in varnishes, scientists are now looking for alternate forms of life. The fact that Deinococcus radiodurans withstood 1000 times the amount of radiation to kill humans, suggests that there might be a life which we do not

Credit & Identity Theft - Research Paper Example You should know all of your payment due dates. Make a list of all your regular due dates and if a bill doesn’t show up, look into it right away. You should always review your medical insurance claims and statements. Medical costs are so high that it would only take one or two fraudulent claims to leave you owing thousands of dollars for treatments someone else received. Another way to protect yourself is to invest in a paper shredder. There is just so much information on so many different bills and statements that can easily fall into the wrong hands. Before you throw away anything with any personal information on it, shred it! Another good idea to take advantage of the three free credit reports that you can access every year. You can space them apart so that you can review a credit report every 4 months. Not only is it important to keep someone from accessing your identity or your credit but it’s just as important that you become aware of it right away. The longer it goes undetected, the longer it will take you to repair your name, your identity and your credit. It’s important to keep in mind that this is a global problem. Last year I got a phone call from my credit card company asking if I had made two charges totally about $1000 in France. They told me that the two charges were actually â€Å"swipes† at two stores in Paris, France which means that someone had actually made up a fake credit card with my credit card number on it and passed it through a credit card machine. Even though they didn’t allow the two charges I felt violated that somehow somebody had gotten my credit card information. Mine was a small case. Some people have been financially ruined with their bank accounts emptied; credit cards â€Å"maxed† out, home and car loans initiated without the victim’s knowledge until it was too late. As I stated earlier, if your identity is stolen it is important that you find out as quickly as
