The ability of Bacteria and Archaea to adapt to new environments as a part of bacterial evolution, most frequently results from the acquisition of new genes through horizontal gene transfer rather than by the alteration of gene functions through mutations. The Horizontal gene transfer actually occurs through transformation, transduction, conjugation and other gene transfer agents in bacteria. 3. The plasmid DNA can be transmitted by horizontal gene transfer to bacteria of same or other species. It is most often thought of as a sexual process that requires a mechanism for the mobilization of chromosomal DNA among bacterial cells.

The foreign DNA is either randomly inserted into the host genome or recombines if there is sequence homology between the two genomes. Physical gene transfer disrupts the cell wall and cell membrane via mechanical means. transcription. Methods of Gene Transfer Bacteria can acquire DNA (i.e., new genes) in 3 basic ways: 1) Transformation • uptake and retention of external DNA molecules 2) Conjugation • direct transfer of DNA from one bacterium to another 3) Transduction • the transfer of DNA between bacteria by a virus C) complicates the construction of phylogenetic trees and the interpretation of specific traits in relation to … Drug resistance genes are often carried on plasmids or in transposons that can undergo vertical transfer easily and between microbes through horizontal gene transfer. 7. Horizontal vs vertical gene transfer The natural transfer of genetic material from one organism to another is referred to as horizontal gene transfer or the lateral gene transfer. Bacteria can take up and spread genes in different ways • Uptake of naked DNA directly from surroundings • Obtain genes from infecting viruses • Take up genes through cross-species mating (c) David Gilbert 2008 Phylogenetic Trees 25 RETURN TO "PROKARYOTIC CELL ANATOMY: PLASMIDS AND TRANSPOSONS" RETURN TO UNIT 1 TABLE OF CONTENTS; Gary E.
