Golden Rice. Ein gentechnisch verändertes Lebensmittel zur - download pdf or read online

By Nora Schrader

Studienarbeit aus dem Jahr 2014 im Fachbereich Biologie - Genetik / Gentechnologie, word: 1,0, Universität Hamburg, Sprache: Deutsch, summary: Die vorliegende Arbeit thematisiert die Möglichkeit, einen weit verbreiteten diet A-Mangel mithilfe einer gentechnisch veränderten Reissorte einzudämmen und diskutiert unter Einbezug verschiedener Ansichten die Chancen und eventuellen Problematiken dieses Vorhabens.
Um mit einem Zitat von Transgen three (o.J.) zu beginnen: „Nach Schätzungen der WHO leiden weltweit rund 127 Millionen Kinder im Vorschulalter an nutrition A-Mangel. Bis zu 500.000 erblinden jedes Jahr, etwa die Hälfte von ihnen stirbt innerhalb eines Jahres nach der Erblindung“.
Tatsächlich leiden viele Heranwachsende vor allem in afrikanischen und asiatischen Ländern, in denen Reis Hauptnahrungsmittel ist, unter einem Vitaminmangel. Reis selber enthält kaum Provitamin A und kann den Tagesbedarf eines Menschen somit nicht decken (vgl. ebd.). Beim Lesen dieser Zeilen entsteht die Frage, weshalb guy den Mangelerscheinungen der betroffenen Bevölkerung in Zeiten gentechnischer Verfahren nicht entgegen wirken kann. In der Tat findet die grüne Gentechnik in der Landwirtschaft und in der Lebensmittelherstellung Anwendung, wird jedoch kontrovers diskutiert (vgl. Krause et. al. 2011). Hier gibt es den Ansatz, in Pflanzen Gene einer anderen Spezies einzubringen, um beispielsweise agronomische Eigenschaften wie Krankheits- und Stressresistenz zu erzielen, oder andere Charakteristika wie Inhaltsstoffe oder Nährstoffzusammensetzungen zu modifizieren (vgl. BioSicherheit 2011). Letzteres wurde im Hinblick auf eine Verbesserung der eingangs beschriebenen state of affairs versucht: Reis wurde mit Beta-Carotin, einer Vorstufe von nutrition A, angereichert und der sogenannte Golden Rice entstand (vgl. Frey 2001: 4-7). Diesen möchte ich in der vorliegenden Arbeit genauer betrachten und folgenden Fragestellungen nachgehen:
Sollte der Golden Rice einen Beitrag zur Deckung des weit verbreiteten diet A-Mangels leisten? Unter welchen Bedingungen wäre dies denkbar?

New PDF release: Non avevo sei anni ed ero già in guerra (Einaudi) (Italian

By Tilde Giani Gallino

Le vicende, narrate in uno stile insolito, a volte scanzonato e ironico, a volte dolente e accorato, riguardano un periodo di undici anni, dal 1934 al 1945, dal prima al dopo guerra. l. a. bambina è coinvolta in vari eventi.

Download PDF by Anders Pape Møller,John P. Swaddle: Asymmetry, Developmental Stability, and Evolution (Oxford

By Anders Pape Møller,John P. Swaddle

Why does nature love symmetry? during this up to date evaluate of symmetry and its evolutionary implications, Anders Møller and John Swaddle argue that symmetry is said to genetic balance and health and that symmetric contributors seem to have quantifiable and critical benefits over their uneven opposite numbers. by contrast, asymmetry, a typical degree of developmental instability, is the results of environmental or genetic disruptions of developmental methods, equivalent to pollution, festival, parasitism, inbreeding, genetic mutation, and hybridization. Møller and Swaddle hold that deviations from morphological symmetry are vital components in social or sexual events: animals are able to use symmetry as a good indication of caliber while assessing power buddies or rivals. This accomplished assessment of the literature on developmental balance should be vital studying for college students and researchers within the fields of ecology, evolutionary biology, genetics, and animal behavior.

Download e-book for iPad: The Adaptive Landscape in Evolutionary Biology by Erik Svensson,Ryan Calsbeek

By Erik Svensson,Ryan Calsbeek

The 'Adaptive panorama' has been a significant inspiration in inhabitants genetics and evolutionary biology on the grounds that this strong metaphor was once first formulated via Sewall Wright in 1932. 80 years later, it has turn into a primary framework in evolutionary quantitative genetics, choice stories in average populations, and in experiences of ecological speciation and adaptive radiations. lately, the easy idea of adaptive landscapes in dimensions (genes or features) has
been criticized and a number of other new and extra subtle types of the unique adaptive panorama evolutionary version were constructed in reaction. No released quantity has but seriously mentioned the prior, current nation, and destiny prospect of the adaptive panorama in evolutionary biology. This
volume brings jointly trendy historians of technology, philosophers, ecologists, and evolutionary biologists, with the purpose of discussing the state-of-the-art of the Adaptive panorama from a number of varied perspectives.

Download e-book for kindle: Kousboek (Dutch Edition) by Gabriel Kousbroek

By Gabriel Kousbroek

`Tot voor kort kreeg ik slechts onder één voorwaarde publicatieruimte van uitgevers en kranten: een exclusief interview met mijn vader en/of mijn moeder. Omdat mijn vader mij voor dit soort omkoperij had gewaarschuwd ben ik er altijd voor op mijn hoede geweest, maar nu hij er niet meer is, is die voorwaarde komen te vervallen.

Gabriël is na het overlijden van zijn vader Rudy, zijn moeder Ethel Portnoy en zijn zuster Hepzibah een van de laatsten van het illustere geslacht der Kousbroeken. Het is tijd om de balans op te maken. Dat doet hij als professioneel tekenaar én als de schrijver die hij door zijn bloedbanden natuurlijk ook is. Eerlijk en genadeloos schildert Kousbroek zijn ouders en de met chicken bevriende schrijvers en vertelt hij over de opmerkelijke incidenten uit zijn jeugd. Waar bloed is, is vuur. De Nederlandse cultuur heeft er een nieuwe Kousbroek bij.
