PCR History The invaluable molecular technique known as PCR, or the polymerase chain reaction, was discovered by a biochemist named Kary Mullis. Mullis was doing research in the early 1980s at a biotechnology company in California when he initially thought of the idea regarding PCR. PCR was developed by a combination of several techniques already in existence; the synthesis of oligonucleotides and their utilization to synthesize new copies of DNA that were specific using DNA polymerases. Mullis…

Distribution of Heavy Metals in the Soil Around Tar Creek Sophia R. Hunt Ariel Diaz Salinas Abstract This experiment is being done to understand how heavy metals are distributed in the soils surrounding Tar Creek. Heavy metals have harmful effects on human health, especially in young people. Mine drainage and multi-story high chat piles left behind in the Tri-state mining district contaminate local Oklahoma waterways, including Tar Creek, with elements such as lead and zinc. Using flood maps of…

As a parent myself, I can imagine the pain and stress they are suffering now. “Her name is Annie. She had a seizure last Saturday” said Angela, a petite woman in a shaky voice. Her…

INTRODUCTION OF PUBLIC HEALTH CONCERN A designer drug is an analog of an illegal drug that has been modified structurally and/or functionally such that it can be sold in the US because the chemical structure of the substance no longer matches a known controlled substance (Wohlfarth 2010). People, especially teens, can purchase these “new psychoactive substances” (NPS) online and from friends, without an understanding of what they are actually taking. Deaths due to designer drugs happen, and…

The leading cause of death for chronic virus infection in the United States is caused by the hepatitis C virus (HCV), an infectious disease that causes liver inflammation. There are five types of hepatitis, hepatitis A, B, C, D, and E, hepatitis C virus being the most serious of the four. HCV is not a sexually transmitted disease; it is contracted through direct contact to infected blood, and from contaminated medical supply. According to the World Health Organization, hepatitis C is most…

Importance of Microbes Introduction It was long ago when Man realized that, along with animals and plants, he was also accompanied by some other organisms as well, and though which remained hidden from his eyes. Those organisms were unveiled by Anton Van Leeuwenhoek, who first saw the tiny organisms which accompanied Man through the lenses of microscope. Later it was found out that microorganisms inhabited each and every surface of earth, on man himself, or even inside him, resided under the…

immersed in acid solutions in the presence and absence of inhibitor for 6 hour at room temperature were taken out washed carefully with doubly distilled water and dried. Then the surfaces were analyzed by using Shimadzu FTIR, Energy Dispersive X-ray fluorescence spectrometer and photographed at appropriate magnification. 3.RESULT AND DISCUSSION 3.1.Preliminary phytochemical screening of 1M HCl extract of Antigonon Leptopus The results of the preliminary phytochemical screening are given in…

Pollution is one of the most serious problems that affect our environment, and its effects on all life aspects are clear to everyone. Because of this, pollution is one of the most serious issues that all the word countries are concerned about. As time goes, the pollution problem increases and also the population growth increase. The increase in demand for water and food supplies place an increasing stress on the ground and surface water quality and quantity. One of the environmental problems…
