This Concept Map, created with IHMC CmapTools, has information related to: Answers_plasmids_transposons, Plasmids and Transposons ???? plasmids, Very important in horizontal gene transfer in bacteria. horizontal gene transfer A process in which an organism transfers genetic material to another cell that is not its offspring., Transposons elements or "jumping genes" are small pieces of DNA that contain a number of genes coding for antibiotic resistance or other traits, flanked at both ends by insertion sequences coding for an enzyme called transpoase. benefit to bacterium Very important in horizontal gene transfer in bacteria., plasmids functions Plasmids that can be transmitted by cell-to-cell contact are called conjugative plasmids. They contain genes coding for proteins involved in both DNA transfer and and the formation of mating pairs., plasmids characteristics Some plasmids, called episomes , are able to insert or integrate into the host cell’s chromosome where their replication is then regulated by the chromosome., transposons integrons Transposons that can carry multiple gene clusters called gene cassettes that move as a unit from one piece of DNA to another., plasmids characteristics Not essential for normal bacterial growth and bacteria may lose or gain them without harm., Plasmids that can be transmitted by cell-to-cell contact are called conjugative plasmids. They contain genes coding for proteins involved in both DNA transfer and and the formation of mating pairs. significance Very important in horizontal gene transfer in bacteria., Transposons elements or "jumping genes" are small pieces of DNA that contain a number of genes coding for antibiotic resistance or other traits, flanked at both ends by insertion sequences coding for an enzyme called transpoase. benefit to bacterium Transposons are able to cut themselves out of a bacterial nucleoid or a plasmid and insert themselves into another nucleoid or plasmid and contribute in the transmission of antibiotic resistance among a population of bacteria., Very important in horizontal gene transfer in bacteria. horizontal gene transfer A process in which an organism transfers genetic material to another cell that is not its offspring., Codes for the synthesis of a few proteins not coded for by the nucleoid. benefit to bacterium Can provide a selective advantage under certain environmental conditions., Plasmids and Transposons ???? transposons, transposons characteristics Transposons elements or "jumping genes" are small pieces of DNA that contain a number of genes coding for antibiotic resistance or other traits, flanked at both ends by insertion sequences coding for an enzyme called transpoase., plasmids functions Codes for the synthesis of a few proteins not coded for by the nucleoid., plasmids characteristics Small, nonchromosomal, circular DNA molecules that replicate independently of the host chromosome.
