Study Guide 4 CH. 21 Genomics – the study of whole sets of genes and their interactions. Bioinformatics – is the application of computational methods to the storage and analysis of biological data Linkage Map – maps the location of several thousand genetic markers on each chromosome Physical Map – Expresses the distance between genetic markers‚ usually as the number of base pairs along the DNA Metagenomics – DNA from a group of species (a metagenome) is collected from an environmental

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

fixation: After a smear has dried at room temperature‚ the slide is gripped by tongs or a clothespin and passed through the flame of a Bunsen burner several times to heat-kill and adhere the organism to the slide. Routinely used with bacteria and archaea. Heat fixation generally preserves overall morphology but not internal structures. Heat denatures the proteolytic enzyme and prevent autolysis. Heat fixation cannot be used in the capsular stain method as heat fixation will shrink or destroy the capsule
