Think That Bacteria Are Bad? Think Again

The readers will perhaps gain new knowledge regarding the importance of bacteria in biology and how they can be benefitial to the population as a whole in developing an antibiotics against virus and other bacteria. This article might also change the perception or introduce the idea to common laypeople that germs and bacteria are different in terms of their use in science. This article shows that bacteria, are not the little thing that make people sick but they are the little thing that prevent or cure them from disease and sickness of some types.

The Use of Bacteria and Plasmids That May Surprise You

Bacteria have been helpful to genetic engineers, not only providing them with restriction enzymes, but also with what are called “plasmids”. These types of research are advancing our way to fight diseases.

For most of time since I was a little child, I have always thought, or have negative connotation toward bacteria that they are all bad for our bodies and they are the definition of dirty. I am sure that I cannot be the only one that think this way about them. So to factoidz this myth I have write this article.

In addition to their single chromosome, many bacteria also contain tiny rings of DNA, called plasmid. Plasmids are usually about one thousand to a hundred thousand nucleotides long and acts as independent self-replicating molecular operators within bacteria. Plasmids are one of the way that DNA recombination goes on within nature. While a bacteria’s chromosome contains all the necessary genes to code for the bacteria’s existence. Plasmids provide an effective way by which traits not contain chromosome can be passed from bacteria to bacteria. For example, some plasmids contain genes that code for enzymes that digest certain antibiotics such as penicillin. This is obviously an advantage to the bacteria. If one of bacteria containing plasmids dies, it breaks open and liberates these plasmids to the outside environment as they are often taken up by other bacteria that then acquire the traits coded for by the plasmids.

Genetic engineers can place liberated plasmid in a solution with restriction enzymes and cut them apart. The engineers then place the gene segment they wish to insert in the solution with the plasmid and then add repair enzymes that joined the pieces of DNA together at their sticky ends. These new plasmids, with the newly inserted genes are then placed with bacteria into a different solution, enables the plasmid to penetrate through the cell wall and membrane of bacteria. The bacteria that are exposed to the plasmids are taken out and grown in the culture for a short time.

But not all the bacteria exposed to the plasmid will absorb them. By exposing the culture bacteria to antibiotic such as ampicillin amoxicillin, this kills off the bacteria that didn’t absorb the new plasmid. Most bacteria that get absorbed the new plasmids continue to grow and thrive in the culture. Scientists continue to grow these bacteria until the insulin or growth hormone produced by them is sufficient to be extracted and purified for use by human patients.

For sure we must remember some bacteria are beneficial.
