2. Bacterial transduction: The genetic transfer in bacteria is achieved by a process known as transduction. Lederberg and Zinder’s (1952) experiment in U-tube Salmonella typhimurium indicated that bacterial viruses or phages are responsible for the transfer of genetic material from one to the other lysogenic and. Binary fission. Binary fission, asexual reproduction by a separation of the body into two new bodies. In the process of binary fission, an organism duplicates its genetic material, or deoxyribonucleic acid (DNA), and then divides into two parts (cytokinesis), with each new organism receiving one copy of DNA. Binary fission is the primary method of reproduction of prokaryotic organisms. Bacteria give off oxygen, they are used to make food (like vinegar or yogurt), they break down dead organisms (and plants use those chemicals to grow), and they can be used to help clean up oil spills. Bacteria in your intestings ccan alsso help you to digest your food. Bacteria reproduce asexually by a type of cell division called binary fission.   In preparation for division, the DNA replicates. Two two daughter-molecules of DNA are push…ed apart by synthesis of new cell membrane between them, so that the cell becomes longer. Asexual Reproduction. Asexual reproduction in bacteria is very simple. The cell increases in size. A double wall develops across the midline of the enlarged cell. The cell separates into two cells at the midline wall. Each cell is then able to function as a separate entity. The process of multiplication can be quite rapid. The bacterium E. coli may double in number every 20 minutes in ideal conditions. If you plot the graph of population over time, you get an exponential increase. View animation of asexual reproduction in bacteria (160 Kb).

The four types of microorganisms that can contaminate food and cause foodborne illness are bacteria, viruses, parasites, and fungi. Disease-causing microorganisms. Bacterial reproduction. Bacteria usually reproduce by a simple form of asexual reproduction called binary fission (splitting into two). This is different from the normal process of cell division in higher plants and animals which starts with mitosis. Bacteria do not have the same sort of chromosomes as these organisms so it is not necessary to have the mechanisms (mitosis) to separate them into groups. Types of sexual reproduction that occurs in bacteria are as follows: Cytologic observations and genetic studies indicate something like sexual reproduction, involving the fusion of two different cells and a transfer of hereditary factors occurs in bacteria although infrequently. Bacteria reproduce by a process known as binary fission, while eukaryote such as animal cells, reproduce by mitosis. In binary fission one bacterium slowly separates into two bacteria which then also divide and the life cycle continues as this process repeats over and over.
