Transformation is the process in which a bacterial cell takes up extracellular DNA. This can be especially useful for bacteria in order to acquire certain traits such as: antibiotic resistance‚ synthesis of catabolites‚ or any other trait that would help improve its survival. However‚ not all bacterial cells are naturally competent (able to naturally take up extracellular DNA). There are several techniques that can make cells artificially competent‚ some of which will be discussed later. Bacterial

Malak Zomrawi 4/9/15 Bacterial Transformation I. Abstract In the lab‚ the purpose is to see if we could move genes using plasmid. As well as getting better understand of transformation methods using shock wave. To see the effects five trays are being used containing LB nutrient broth. The results showed that the LB‚ ampicillin‚ and arabinose with a positive pGLO had the most amount of growth compared to the other four trays. Although when there is arabinose there is no fluorescence‚ fluorescence

BACTERIAL TRANSFORMATIONS USING PVIB II. INTRODUCTION Transformation is the manipulation of a bacterial cell’s DNA in order to alter the cell’s genotype or phenotype by absorbing free DNA from its surroundings. In this lab‚ pVIB plasmid will be used. A plasmid is a segment of DNA that can incorporate itself into the bacterial DNA. Although is not required for growth of the bacterial cell‚ plasmids can provide advantages in stressful environments such as the ability to adapt as environmental

Change and Transformation The setting of Nathaniel Hawthorne’s “The Scarlet letter” is crucial to the understanding of the event that takes place in the story. The setting of the story is in Salem‚ Massachusetts during the Puritan era. During the Puritan era‚ adultery was taken as a very serious sin‚ and this is what Hester and Dimmesdale committ with each other.

Burke and Rousseau: Inequality and Transformation During the Enlightenment‚ many western political and economic philosophers attempted to describe the transition of mankind towards modernity. Specifically‚ Edmund Burke (1729-1797) and Jean-Jacques Rousseau (1712-1778) were both heavily influenced by the American Revolution (1775-1783) and French Revolution (1789-1799)‚ which compelled each to write about the existence of inequalities in society and transformations that aim to address these inequalities

Mezirow’s Theory of Perspective Transformation Mezirow’s Theory of Perspective Transformation Adults today are the products of their individual histories and experiences‚ which influence their attitudes‚ thinking processes‚ and conceptualization of their worlds. John Mezirow believed that adults can be transformed from these experiences; however‚ the transformative learning involves critical self-reflection (Mezirow‚ 1990). Mezirow understood that adults can be transformed through a process

Introduction Transformation is a genetic alteration of a cell resulting from the direct uptake and incorporation of exogenous genetic material from its surrounding through the cell membrane. The arabinose operon changes AraC from a repressor to an activator; in this experiment the pGLO plasmid has been designed with a modified operon so that in the presence of the arabinose the bacterial cells which have been transformed by the pGLO plasmid will fluoresce due to the production of GFP.

Baz Luhrmann’s Romeo and Juliet Transformation A hugely successful transformation of the complex written version to the action packed film took place when accredited writer Baz Luhrmann redefined the classic tale of Shakespeare’s Romeo And Juliet. Luhrmann and co-writer Craig Pearce were tenacious in deciding "to stick absolutely to the Shakespearean text‚ to keep as many of the Elizabethan customs as possible‚ such as a highly evolved code of etiquette and honor‚ even in the use of violence" in
