genetic engineering and transformation of bacteria. The characteristics of bacteria are altered from an external source to allow them to express a new trait‚ in this case antibiotic resistance. In is experiment foreign DNA is inserted into Escherichia coli in order to alter its phenotype. The goal of the experiment is to transform E. coli with pGLO plasmid‚ which carries a gene for ampicillin resistance‚ and determine the transformation efficiency. The bacteria are transformed by a combination of calcium

its DNA and is known as a common mutagen. Prediction: If UV light mutates the DNA of Serratia Marcescens then the red pigment colonies of the bacteria will no longer be produced. Independent Variable: Ultra Violet Radiation Dependent Variable: The color change of the bacteria Serratia Marcescens from red to white and the survival of the bacteria. Control: Nutrient agar plate with streaks of Serratia Marcescens without exposure to UV light. Results:

Definition noun‚ singular: eubacterium Literally means true bacteria‚ which includes all bacteria except for archaebacteria. Supplement These bacteria form the domain Bacteria‚ previously called domain Eubacteria. It is one of the three domain systems‚ the other two being domain Archaeabacteria (now Archaea) and domain Eukarya (the eukaryotes) -Eubacteria are also prokaryotic and reproduce asexually. -They are the most common bacteria found almost everywhere in the world. -Eubacteria have Peptidoglycan

young life that has been taken by the infection of a killer disease. It’s a painful thought to know that person never got to live to see their full potential. Diseases kill children every year. Many diseases are bacteria‚ inhaled by the victim‚ infecting several areas of the body. The bacteria lives and grows while its victim dies. Other diseases are caused by viruses; a non-living infection that attacks the disease-fighting system and other living cells. Children are much more able to be hurt by disease

and Staphylococcus albus Some bacteria’s require a certain amount of light in order to function properly and there fore survive. Escherichia coli is found in the gut and intestines of mammals. Staphylococcus albus is generally a skin dwelling bacteria Aim: To test whether the amount and type of light that the bacteria’s E.coli and S.albus are subject to causes changes in their growth rates and habits. To test whether the growth rates and habits of the bacteria’s E. coli and S. albus are

important biological functions living organisms are capable of carrying out. Although a cell may have thousands or hundreds of thousands of genes‚ only the ones needed this is determined by the environment are turned on at any given time. In bacteria‚ temperature‚ pH‚ and other chemical agents all affect the expression of genes. In this lab‚ the effect of temperature change on the gene which codes for a red pigment called prodigiosin of bacterium Serratia marcescens is being tested. Serra

This semester while we worked through this unit‚ we were trying to figure out why Addie got so sick and how we could look at the juncos as a comparison study. We learned about the relationship that antibiotics and bacteria have by looking at our NetLogo Simulation and Petri Dish Lab. Also‚ we learned about various CDC recommendations for using antibiotics and preventing bacterial illnesses. When we looked at the juncos‚ we were able to learn how common ancestry works within any species. Throughout

Title Laboratory 3: Examination of Living Bacteria Introduction Unstained bacteria are difficult to observe because of the lack of contrast between the cells and the surrounding. To see them in an unstained state and also to observe their motility‚ a hanging-drop or a wet mount technique is used. A wet mount is the technique of placing small amounts of specimen in a droplet of water for viewing with the compound microscope. Motility is an inheritable phenotype and is critical for identification

Helicobacter pylori is bacteria that resides within the body of an individual‚ specifically living in the digestive tract. The bacteria is initially transferred from mother to child and typically resides in the body until death‚ but complications may arise such as gastritis which is the inflammation of the stomach as well as diseases within the stomach such as Crohn’s disease. Although‚ many bacteria can be classified as dangerous to body because of its ability to invade the body and induce infection

Unknown Project I. Introduction The purpose to this lab was to isolate and identify two unknown bacteria from a mixed culture provided to us. This study was done by applying all of the methods that have been instructed on thus far in microbiology laboratory class. Each test performed‚ provided us with some key information about the unknown microbes in question . The identification of unknown bacteria is a time honored part of microbiology courses. It will challenge knowledge and skill in performing
