13 Mar Improved Quality of Life Through Biotechnology
Biotechnology is an industry involving the manipulation of DNA to create more desirable molecules. Mendel’s work with pea plants determined that living things do share traits. Geneticists study the nature of DNA in order to better understand heredity of several species. Recent genetic engineering practiced in the lab are found in the supermarkets as genetically modified vegetables. Certain diseases are combated with DNA altered in the laboratory. Biotechnology is the field of perfecting life.
Genetically Modified Foods
Early experimentation with genetic manipulation took place in the field of agriculture. The first plant successfully manipulated and provided to the public was the tomato. In the 1990’s, the goal was to create a fruit that maintained freshness, flavor, and withstood insects and insecticides. Scientists were able to provide an altered crop and feed more people. Since 1994, genetically modified foods such as soybeans, corn, rice, and wheat are just a few more edible clone crops to grace U.S. grocery shelves without disclosure.
Vaccines and Chromosome Mutation
Vaccines are an example of genetically altered diseases. Scientists were able to study the DNA and evolution of certain infections, realign the sequencing, and combat germs with mutations of germs. Currently, genetic research is dedicated to understanding the cancer cell. Unfortunately, there is not only one such cell. Cancerous tumors have the ability to evolve and change on a molecular and cellular level which stumps blanket combative progress.
Many vaccines, such as those for Polio and Chicken Pox, include impotent varieties of the original virus. Once injected into the person, the altered disease form defeats any previously threatening version of itself. Great strides have been made against prostate and breast cancers in the lab as far as defining the chromosome mutation that typically precedes the diseased outbreak. However, there is much more to learn and biotechnology provides the basis for moving toward new health regimens.
The Science of DNA and Cloning
Whether in farming or medicine, comprehending the language of DNA as it functions within in each cell serves to improve the industry. Scientists isolate cells in compliant samples of certain bacteria. For instance, bacterial plasmids reproduce independent of the larger bacterial chromosome. Because of this, they transport most genes without effort and mass produce altered sequences.
The clones consist of similar genetic frames but differ from the original gene just enough to improve the situation. Improvement could mean higher crop yields or more effective health care. Enzymes within bacteria exist to cut away targeted sequence and once the scientist confirms the particular relationship, he can use the enzyme to create a gene sequence that benefits his species. The ripe, hard, tasty, and bug resilient tomato crops are the result of gene manipulation.
Biotechnology and Gene Manipulation
Making recombinant DNA involves snipping away segments that deter the final message. Like making a collage, one cuts pieces of the magazine away to make a picture or note of his own. Fitting pieces together from different DNA particles forms a functional bit of genetic material for further use.
Scientists study the natural mutations of chromosomes and master their own mutation to protect the cell from threat. Biotechnology employs the understanding of the human cell systems, DNA formation, disease forms, and the use of enzymes to enhance health or combative strategy.
