Viruses can infect all types of cells including plant‚ animal‚ protozoa‚ fungi‚ and bacteria. Virus composition is unique and does not resemble a living cell because they only contain the necessary parts to enter and leave an infected cell. A virus is a minute parasite (10 to 100 times smaller than bacteria) that is unable to reproduce by itself; however‚ once it infects a vulnerable cell a virus can make the cell’s inner workings produce viruses on its behalf. Viruses typically have either RNA

Modern Day Example of Natural Selection – Antibiotic Resistant Bacteria Read pg 112 -113 & 275 – 277 of you text book. Use this information plus information from secondary sources to answer the following questions so you will have a case study on antibiotic resistant bacteria. In this case study you will need to show how an environmental change can lead to a change in a species. Note: this will also cover content in the Search for Better Health topic. 1. Outline the purpose of anti-biotics

I. Title Identification of an Unknown Plasmid In this experiment‚ we determined the phenotypic capability of an unknown plasmid along with its size. With the use of gel electrophoresis‚ we analyzed the gel photograph by using a standard DNA marker‚ Lambda HindIII‚ and came to a conclusion based on our results. II. Abstract Two experiments were done to identify an unknown plasmid. The success of these experiments came from the use of modern day technology involving gel electrophoresis

Bacteria: a benefit or a hazard? Bacteria is something we are all reminded of on a daily basis by merely switching on our televisions where we are bombarded with advertisements for both ‘good’ and ‘bad’ bacteria. Contrary to the view of the past when only so-called ‘bad’ bacteria was ever talked about‚ so what has changed? This essay will address the facts about bacteria including methods used in identifying bacteria as well as looking at specific examples of how they can be both helpful and harmful

Effects of Different Antibiotics on Bacteria Because of their small size‚ rapid rate of reproduction‚ and relatively simple structure‚ bacteria are excellent subjects for laboratory studies. This investigation will introduce you to techniques of microbiology that will be of use to you throughout your biological work. Procedure 1. Heat the test tubes of sterile agar medium in the water bath until the agar melts. 2. Remove the test tubes from the water bath. Let them cool enough to hold in your

Many types of projects are possible when you are able to count bacteria. For example‚ you could count the bacteria in drinking water‚ fresh milk‚ old milk that is slightly sour‚ buttermilk‚ yogurt‚ mud puddle‚ lemonade‚ and many other things. Or you may want to know how fast Chlorox kills bacteria. If you add some Chlorox to a culture and count the surviving bacteria at suitable intervals you can plot killing the killing curve and determine whether the killing is single hit or higher order. It will

Antibiotics attack bacteria by targeting a protein‚ or stopping the creation of a cell wall and or how they metabolize sugar. This method of targeting the specific functions of bacteria have allowed antibiotics like Penicillin to save millions of live throughout in the past few decades. As amazing as antibiotics are they have a really smart enemy. Bacteria are cleaver little single-celled organisms. Bacteria can actually barf up the antibiotics we use to fight them. The genetic information bacteria gather in

Anaerobic respiration in Bacteria Like humans and other animals‚ bacteria need to breathe. Anaerobic bacteria basically mean bacteria that respire anaerobically. All living cells need to respire in order to release energy for vital cell activities. Anaerobic respiration is respiration in the absence of oxygen‚ hence anaerobic bacteria does not breathe at all. The purpose of respiration is to provide the cell with the appropriate molecules for creating energy in the form of adenosine triphosphate

Flesh-eating bacteria strikes in Florida On June 16th‚ 26 year-old Cason Yeager went for a swim in Florida in Hernando County and later died from contracting the flesh-eating bacteria‚ Vibrio Vulnificus. This bacteria can be found worldwide‚ most particularly in the warm coastal regions but there have been reports in other parts of the world in non-warm waters. According to the CDC in 2013‚ the case count of the vibrio vulnificus was 104 in thirteen states with six hospitalizations. No deaths‚ but
