Vancomycin- resistance gene (encoded on a transposon on a plasmid) Plaşmid Staphylococcus aureus sensitive to vancomycin Enterococcus faecalis plasmid transferred by conjugation Enterococcus faecalis resistant to vancomycin Transposon jumps from one plasmid to another. Plasmid from Enterococcus faecalis is destroyed. FIGURE 1 Transfer of Vancomycin Resistance from Enterococcus faecalis to Staphylococcus aureus Transfer of resistance involved both a plasmid and a transposon. Vancomycin-resistant Staphylococcus aureus ? What role did the transposon play in the transfer of resistance?
Genetic Recombination
Recombination is crucial to this process because it allows genes to be reassorted into diverse combinations. Genetic recombination is the process of combining genetic components from two different origins into a single unit. In prokaryotes, genetic recombination takes place by the unilateral transfer of deoxyribonucleic acid. It includes transduction, transformation, and conjugation. The genetic exchange occurring between homologous deoxyribonucleic acid sequences (DNA) from two different sources is termed general recombination. For this to happen, an identical sequence of the two recombining molecules is required. The process of genetic exchange which occurs in eukaryotes during sexual reproduction such as meiosis is an example of this type of genetic recombination.
Microbial Genetics
Genes are the functional units of heredity. They transfer characteristic information from parents to the offspring.
