resistance occurs when an antibiotic is no longer effective against a particular bacteria‚ making that organism resistant to the effects of the antibiotic. Bacteria become resistant due to selective pressure. Those organisms which resist the antibiotic‚ and do not die from it ’s effects have a greater chance of survival within the host‚ therefore allowing them to reproduce and spread it ’s resistance to other bacteria. while the ones susceptible to the antibiotics die. This can be caused by unnecessary

Lecture 14 Lecture Gene Complementation in Bacteria In order to perform tests for dominance or for complementation in bacteria we need a way to make the bacteria diploid for part of the chromosome. To do this we need to consider a different extrachromosomal element: Ori T The F plasmid (length 105 base pairs) Tra genes There are some special terms to describe the state of F in a cell: F– refers to a strain without any form of F‚ whereas F+ refers to a strain with an F plasmid. F‚

Question: Suppose a meteor impact blows some extremophile bacteria from the Earth into the depths of a gas giant planet called planet X ‚ where they evolve into an intelligent species which practises physics. Do you think their physical theories would be similar to ours‚ and if so in what ways would they be likely to be similar? Your answer will necessarily involve some speculation‚ but make sure it involves some careful argument as well. Theoretical physics is one of many braches of physics that

Cells Now we need to discuss CELLS. You’ve probably heard of cells‚ and may even know of a few‚ such as blood cells‚ nerve cells‚ or skin cells. What are these things called cells? Cells are the smallest living things. You’ll be learning a lot about cells in this course. For now‚ however‚ I’ll introduce you to just a few basic things about them. Cells are extremely tiny organisms that carry out all of the functions of life inside a thin layer of “skin” called (unimaginatively) the CELL MEMBRANE

Discussion Board Question 7 THE CASE OF BRIAN B. AND THE MEDICAL FILE TEST Brian B. is taken into an exam room in the office of Dr. K. by the medical assistant‚ Amy. Amy gets into an animated discussion with Brian about their mutually favorite baseball team. As Amy leaves the exam room‚ she accidentally places Brian’s medical file on the counter. While Brian waits for Dr. K.‚ he reads through his file folder. He is shocked to discover that his recent test for AIDS came back positive. Brian

health and is easily infectious with contaminated sustenance. E. coli is gram-negative bacilli tested in clinical settings from stool specimens. The tests detect the presence of disease causing pathogens of E. coli that produce Shiga toxins. E. coli bacteria commonly occur in nature and they are a necessary component of the digestive process in humans and most other mammals. Most strains of E. coli are harmless‚ but pathogenic E. coli can be responsible for inflammation of the stomach and intestines

Discussion In the model systems (solutions and paper)‚ which samples browned the fastest and why? Which samples did not go brown and why? Why did the paper brown so rapidly compared to the solutions. What caused any significant differences between the model and real systems? In particular are there other ingredients in the cookie that could take part in the reactions or is the heating different in some way? Sample A and sample B are overlap after fry the paper. Sample B is more browning

You were graded on this activity separately. After you have isolated your gram negative in pure culture you will be subjecting it to various biochemical tests and making observations about the cells‚ colonies‚ growth temperature preferences‚ etc. in
