Sexual reproduction of bacteria Only an in-depth knowledge of the essence of sexual reproduction - as a process in which a new record is created with the genetic characteristics of organisms genealogical records - led to the discovery of sexual reproduction in bacteria. At the same time, the study of these processes at the micro-organisms has allowed to prove that DNA is the carrier of hereditary characteristics. The transformation was discovered in 1928 by F. Griffith he ran the tests on dominance pneumonia (Staphylococcus pneumonia). These bacteria produce a coating made of saccharides In the light of this, of which sugar is made sheath, split There are various types of pneumonia. Twinkie with a coating are pathogenic, and after the injection, the animal dies. Transferred in the process of transforming the DNA fragment of the chain may come from the nucleotide and the bacteria is mainly engaged into the second nucleotide. There are, however, DNA molecules, which in the cell are separated from the bacterial Genovera Since there are in the cytoplasm, they are called plasmids. Plasmids can be transmitted much more frequently from one bacterial cell to another and ensured that the bacteria acquire new properties.
