What does transformation involve in bacteria




















What is a bacterial transformation? What does transformation do in bacteria? What is meant by bacterial transformation? In his transformation experiments what did Griffith observe? What is the similarity between conjugation and transformation?

How did transformation contribute to the information known about genetics? How can cells become transformed? What is the difference between transformation and conjunction of bacteria? Subsequently, the whole process of genetic cloning has opened up a new field of genetic manipulation. Thanks to genetic cloning, researchers can manipulate bacteria to produce large amounts of specific human proteins, such as insulin to treat diabetes patients Cloning also has served a major importance in modern day agriculture.

Genetically modified organisms GMO are a direct result of genetic cloning and bacterial transformation For instance, scientists are working to generate genetically modified crops with nitrogen-fixing genes incorporated into their genome to boost food production and reduce fertilizer use, thus, diminishing the economic and environmental impact of fertilizers In sum, bacterial transformation is the first step of modern-day biotechnology and the foundation of future research discoveries.

Bacterial Transformation using Plasmids Bacteria are the ideal organisms for transformation as they can easily take in exogenous genetic material into their genome and quickly amplify it 3,5. Applications Effective transformation methods enabled scientists to isolate and profile genes and gene products and led to many advancements in life sciences and medicine, such as development of effective drugs, generation of genetically-modified crops, and advanced diagnostic tools F, Griffith.

Microbiol Mol Biol Rev. Bennett, PM. Bacteria may sometimes contain smaller circles of DNA, called plasmids, which have a much smaller number of genes.

Plasmids can be swapped between bacteria in a process called conjugation. Plasmids can be used as vectors to carry foreign DNA into a cell. In the lab, plasmids are specifically designed so that the DNA they contain will be copied by bacteria.

Laboratory-designed plasmids contain a small number of genes that help transformation. These include:. The piece of DNA or gene of interest is cut from its original DNA source using a restriction enzyme and then pasted into the plasmid by ligation. The plasmid containing the foreign DNA is now ready to be inserted into bacteria.

This process is called transformation. Before transformation, bacteria are treated with a chemical called calcium chloride, which causes water to enter into the cells and makes them swell.
