What is transformation? * Movement of a gene from one organism to another 2. What did Griffith show? * Showed either protein or DNA causes transformation 3. What did Avery show? * Showed that DNA causes transformation or that DNA is hereditary material 4. What did Hershey & Chase show

translation in the ribosome‚ then there will be unique proteins created‚ too. This allows there to be more types of proteins in an organism than types of genes in an organism’s genome. Repressor proteins can influence the regulation of protein synthesis by binding to operators (the segments of DNA that act as switches to either allow or prohibit RNA polymerase to create mRNA strands) in an operon. Since repressors block transcription of genes‚ many mRNA strands that could’ve been made would not

2.1 Synthesis of p-Toulichydrazone and Resacetophenone Schiff base (RAPPTH): p-Toluic hydrazide (1.5018g) and Resacetophenone (2‚4Dihydroxyacetophenone)(1.5215g) were dissolved in methanol and Refluxed in the presence of few drops of acetic acid for 7 hours on water bath with constant stirring. The resultant mixture was transferred in a china dish and allowed to cool naturally. Light brown crystals were obtained. The compound was recrystalized from water. The % of yield was 80%

nanotubes can be prepared by extraction of this nanoparticles from their source. This study is concerned with extraction of intracellularly produced silver nanoparticles from the fungus Verticillium terrestre . Further innovations in this nanoparticles synthesis are also included in this project.. INTRODUCTION: The study of nanomaterials(1nm=10-9m) has increased a lot due to their fundamental properties‚ organizations to appear as superstructures. Nanoparticles are having many applications such

Experiment 13: Synthesis of 1- Bromobutane An SN2 Reaction Theory: One of the methods of preparing alkyl halides is via the nucleophilic substitution reactions of alcohols. Alcohols are inexpensive materials and easy to maintain. However‚ they are a poor leaving group the OH group is a problem in nucleophilic substitution‚ this problem is fixed by converting the alcohol into H2O. Objective: The objective of this lab is to observe the synthesis of 1-bromobutane in an SN2 reaction‚ to see how

Williamson‚ Macroscale and Microscale Organic Experiments‚ 2nd Ed. 1994‚ Houghton Mifflin‚ Boston p385 Revised 10/15/03 Prelab Exercise: Give the detailed mechanism for the acid-catalyzed hydrolysis of methyl benzoate. Introduction: The ester group is an important functional group that can be synthesized in a number of different ways. The low-molecular-weight esters have very pleasant odors and indeed are the major components

The objective of this experiment was the synthesis of Isopentyl Acetate using an esterification reaction between acetic acid and Isopentyl Alcohol‚ using a strong acid as a catalyst. The product was washed‚ and distilled. This approach is called Fisher esterification‚ whereby esters are produced by the esterification of a Carboxylic acid where it is heated with an alcohol in the presence of a strong acid which acts as a catalyst. The ester produced had a banana flavor. The extraction of the

1 “The Allegory of the Cave” and “Shooting an Elephant” seems like two completely different stories. Both of them have their own ways of showing enlightenment and ways of perceiving realities. After reading both of these tales multiple times‚ I’ve drawn some conclusions on the different ways of enlightenment that are described throughout each story. In “Shooting an Elephant‚” Policeman Eric Blair is asked to kill the elephant that was ravaging the village. Many times he would describe how he

Death Penalty Ignorance Widely discussed all over the world‚ the death penalty has caused much conflict with personal and spiritual beliefs. But how much does the public really know about the death penalty? How are the societal stereotypes on the death penalty affecting the public’s views about it? Before taking a stance on the death penalty‚ individuals should consider what might be new information to them. This includes the brutalization effect‚ the lack of deterrence in the history of the court
