Environmental effects and maintenance mechanisms explores the possibility of the usefulness of plasmids and transposons in controlling pollution. The articles in the book present evolutionary and ecological perspective on the topic. Elizabeth cancer institute, heydukova 10,sk81250 bratislava, slovakia. Types of transposons transposable element molecular genetics. Plasmids code for synthesis of a few proteins not coded for by the bacterial chromosome. However, transposons may have been beneficial for their hosts as genome evolution drivers, thus providing an example of molecular mutualism. Learn vocabulary, terms, and more with flashcards, games, and other study tools. It usually occurs naturally in bacteria and is some times found in eukaryotic organisms e. Recombinacion, transposones y retrovirus slideshare. Types of transposons viiinot all dna transposons transpose through the cutandpaste mechanism. Introduction of plasmids, their importance and types plasmids are transferable extrachromosomal dna molecules capable of autonomous replication. Since transposons take advantage of their hosts cellular machinery to proliferate in the genome and enter new hosts, transposable elements can be viewed as parasitic or selfish dna.
