Abstract Some bacteria are able to go through transformation making new combinations of genes. Transformation is a way of gene variability in bacteria. This experiment is based on the transformation mechanism of bacteria and gene regulation. The bacteria used for the experiment was Escherichia coli and the genes introduces for the transformation were: gfp and bla by a pGLO™ plasmid. After the insertion of the target genes and growing the bacteria on specialized LB media‚ it could be seen that the

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‚

1. To distinguish the bacteria abilities to metabolize various substrates and end products formed. 2. To observe the growth of different bacteria species in term of structures and its morphology based on different chemical substance applied. 3. To observe physiological and immunological properties utilized by different species of bacteria. INTRODUCTION: Bacteria biochemical testing can determine the types and numbers in terms of colony forming units of bacteria present in a sample of different

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

This experiment worked with enteric bacteria which are members of the Enterobacteriaceae and live in the intestinal tract (Willey et al.‚ 2014). Also found in Willey et al (2014) is some characteristics of enterics such as they all degrade sugars by means of the Embden-Meyerhof pathway‚ they

The microscope parts and capabilities were clearly identified and used successfully and the bacteria were clearly illustrated showing the bacterial shapes and arrangements with all the appropriate magnification being utilized. Through various magnifications using 10x‚ 40x and 100x oil immersion lenses‚ the bacteria specimens‚ along with fresh and prepared yogurt‚ demonstrated full visual optical views

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

his experiment was done to find out if garlic is effective in killing bacteria. This will help us understand the effectiveness of home remedies such as the use of natural herbs (including garlic) for medicinal purposes. Hypothesis Garlic will kill bacteria and prevent its further growth. Background Herbs and spices have traditionally been used in cooking as they add flavor to our food. These herbs and spices have also been known to many cultures for their medicinal properties. The oils that are
