Gene Cloning Methodology of DNA What is DNA? DNA was discovered by the Swiss biochemist‚ Johann Friedrich Miescher‚ in 1869‚ while he was working in Tubingen‚ Germany. He found that the DNA molecule is large; acidic in nature and rich in phosphorus‚ but only in the 1930s was the real and complex structure of DNA fully studied. DNA (deoxyribonucleic acid) is the genetic material in all prokaryotes and eukaryotes‚ i.e. it is the material responsible for the transfer of hereditary traits from

Examples: Nitrifying bacteria‚ Sulfur-oxidizing bacteria‚ Iron-oxidizing bacteria‚ Knallgas-bacteria photolithoautotrophs obtain energy from light and carbon from the fixation of carbon dioxide‚ using reducing equivalents from inorganic compounds. Examples: Cyanobacteria (water (H2O) as reducing equivalent donor)‚ Chlorobiaceae‚ Chromatiaceae (hydrogen sulfide (H2S) as reducing equivalent donor)‚ Chloroflexus (hydrogen (H2) as

Bacterial Fermentation Secondary article Article Contents Volker Mu¨ller‚ Ludwig-Maximilians-Universita¨t Mu¨nchen‚ Munich‚ Germany . Introduction Under anaerobic conditions‚ in the dark and in the absence of electron acceptors‚ organic compounds are catabolized by strictly anaerobic or facultatively anaerobic bacteria by internally balanced oxidation–reduction reactions‚ a process called fermentation. In fermentation‚ the organic compound serves as both electron donor and acceptor‚ and adenosine

Bacterial Diversity Project John FreesackSection A24 Kim Daffer‚ John Chang September 23‚ 2012 Introduction: Bacteria are everywhere. Some can be seen with the naked eye and some require a microscope but how do we distinguish one kind of bacteria from another? To answer this question‚ we were required to complete three bacterial labs that helped us to understand what microorganisms are and how to identify and classify them. Thus‚ the main purpose of this project is to identify our unknown microorganisms
