DNA Recombinant and How it Helps Certain Companies Produce Certain Drugs
Technology has flourished and has improved our way of living in many ways than one. In the medical world, it has definitely shaped our ways to helping patients through medication. For instance, diabetes, or growth and clotting disorders among the spectrum of human diseases related to protein absence or malfunction. A lot of the medications that we use today are created from bacteria, yeast, insect cells, and mammalian cells, which boost the production of the protein within the human body. For example, insulin is a very in demand medication due to the increase of diabetes as a disease. Before technology, insulin would
Each human being has something called DNA. DNA is described as genetics and an extremely long macromolecule that is the main component of chromosomes and is the material that transfers genetic characteristics in all life forms. DNA constructs of two nucleotide strands coiled around each other in a ladder like arrangement with the sidepieces composed of alternating phosphate and deoxyribose units and the rungs composed of the purine and pyrimidine bases adenine, guanine, cytosine, and thymine. Each chromosome consist of one continuous thread-like molecule of DNA coiled tightly around proteins and contains a portion of the 6,400,000,000 basepairs that make up your DNA.
Medicine has been developed and discovered for thousands of years; however, the 1920’s was the first decade that fashioned a pathway for new developments and discoveries. Medical professionals have taken a huge hit for their fight in finding new inventions that can save patients from death’s hands. In the 1920’s, medicine has also taken a tremendous leap in controlling fatal diseases such as diabetes (Pendergast 110). Medicine in the 1920’s has altered the way medicine is shaped today; furthermore, the development and discovery of the iron lung, penicillin, and insulin were the first pertinent breakthroughs in medical history (“Iron” par. 7; Grimsley par. 15; “Banting” par. 13).
The healthcare industry has had many challenges in the Progressive era especially being not as advanced as it is today. Several health dangers were almost impossible to control, and cure due to lack continuing advancements. The medicines that were used in early times had minimal effects on the many diseases that were out there. Today’s modern medicine has come a long way from new technologic advances to new pharmaceutical meds arriving in record time.
Discoveries in DNA, cell biology, evolution, biotechnology have been among the major achievements in biology over the past 200 years with accelerated discoveries and insights over the last 50 years. Consider the progress we have made in these areas of human knowledge. Present at least three of the discoveries you find to be most important and describe their significance to society, health, and the culture of modern life.

The improvement of medicine over the course of the human successes gave great convenience to the people of today. Science has cured and prevented many illnesses from occurring and is on its way to cure some of the most dreadful and harmful illnesses. As the world modernizes due to the industrialization, so does the ways of medicine. Some cures are approached by chance, some, through intense, scientific measures.
With the huge diversity and changeability of human biology, it is impossible to imagine a reality without some mutations, changes, or issues in the organs and tissues of humans. Thus, it rightly follows that medications and pharmaceuticals have been created in an effort to counteract the various ailments and illnesses that people can experience. However, as time has gone on and these pharmaceuticals have become more and more high-tech, regulated, and trusted, they have also become incredibly commercialized. Worse still, medications have become incredibly expensive and can be unattainable for some people.
With all of the technology improvements and advances we are able to fight and protect more effectively against ermiging diseases.
In the past three decades, scientists have learned how to mix and match characteristics among unrelated creatures by moving genes from one creature to another. This is called “genetic engineering.” Genetic Engineering is prematurely applied to food production. There are estimates that food output must increase by 60 percent over the next 25 years to keep up with demand. Thus, the result of scientist genetically altering plants for more consumption. The two most common methods for gene transfer are biological and electromechanical. “Early experiments all involved changing DNA using bacterial vectors”(Randerson, 2001). Through other advances scientists proclaim how they can improve the human gene pool. All humans have
Cereal storage proteins ( mainly prolamines) have poor nutritional quality because of lower levels of essential amino acids such as lysine, tryptophan and threonine. on the other hand, Grain legume storage proteins, consist chiefly of globulins which are deficient in sulphur-containing amino acids, methionine and cystein. To enhance the seed protein quality two genetic engineering approaches have been used. In the first case, a transgene was transferred for protein containing sulphur rich amino acids into pea plant (which is deficient in methionine and cysteine, but rich in lysine) using a seed specific promoter. In
Medical technology is advancing at a rapid rate. For example, a very common procedure is an endoscopy and colonoscopy which checks for bowel and stomach cancers and some other conditions. New technology is being trialed at the moment, instead of a patient going under an anesthetic and having to have a special diet and bowel preparation prior to the procedure, this will now be done by taking a capsule in a tablet like form where the patient will swallow the capsule that contains a tiny camera and batteries and then be later eliminated by the patients natural bowel movements. This is swallowed by the patient and will travel through the gastro intestinal system, taking
The practice of medicine has been shaped through the years by advances in the area of diagnostic procedures. Many of these advances were made possible by scientific breakthroughs made before the 20th century. Modern medicine arguably emerged. Both normal and abnormal functions (physiology and pathology) were increasingly understood within smaller units, first the tissues and then the cells. Microscopy also played a key role in the development of bacteriology. Physicians started to use stethoscope as an aid in diagnosing certain diseases and conditions. New ways of diagnosing disease were developed, and surgery emerged as an important branch of medicine. Above all, a combination of science and technology underpinned medical knowledge and
Back in the 1200’s the human race had just discovered the circulation of blood. That shows how far we have come with modern medicine. Things like vaccines and even genetics such as DNA would never have been discovered if it was not for
Medical breakthrough of the 1950’s created a healthier environment for Americans and the world. In the early 1950 through many scientific studies and efforts Anti-biotics were created . thus, began the control of bacterial infection. Many treatment drugs and surgical procedures were invented to help Americans deal with Arthritis, Diabetes, Heart disease and Cancer. A step toward a healthy tomorrow for many of those afflicted with these, until now, untreatable areas.
Emerge of recombinant DNA technology provided an immense potential in the field of plant transformation. Transgenic plants detection in most crop species in order to minimize regeneration of non-transformed tissues after transformation requires the use of selectable marker genes and selective agents. The commonly used selectable markers in plant transformation systems are genes conferring resistance to toxic compounds such as herbicides or antibiotics. The negative selectable marker genes routinely used in Nicotiana tabacum transformation are genes that confer resistance to the antibiotic kanamycin. However, the presence of these genes or the derived proteins are undesirable in crop plants grown in the field, because of the public concern
