Genetic Engineering The engineering of deoxyribonucleic acid DNA is entirely new, yet geneticsas a field of science, has fascinated mankind for over 2, years. Man has always tried to bend nature around his will through selective breeding and other forms of practical genetics.
Today, scientists have a greater understanding of genetics and its role in living organisms. Unfortunately, some people are trying to stop further studies in geneticsbut essay on genetic engineering research being conducted today will serve to better mankind tomorrow. Among many benefits of genetic engineering are the several cures being developed for presently incurable diseases. Genetics has also opened the door way to biological solutions for world problems, as well as aid for body malfunctions.
Genetic engineering is a fundamental tool for leading the world of medicine into the future; therefore, it is crucial to continue research in this field. Today's research in genetic engineering is bringing about new methods for curing and treating major medical illnesses.
The Human Genome Project has essay on genetic engineering geneticists to map the genes of human beings. This project is far from complete, as the DNA sequence of humans is extremely long, yet it will eventually show geneticists which genes are responsible for certain inherited AmirAshkan Semyary By using the techniques of genetic engineering scientists are able to modify genetic materials so that a particular gene of interest from one cell can be incorporated into a different cell.
It is necessary to obtain a gene to modify genetic material. First a scientist isolates plasmid DNA from bacteria and DNA carrying a gene of interest from cells of another organism, such as an animal. A piece of DNA containing the gene is inserted into a plasmid, producing recombinant DNA, and the recombinant plasmid is returned to a bacterial cell.
This cell is then grown in culture forming a clone of cells. The foreign DNA spliced into the plasmid is replicated with the rest of the plasmid as the host cell multiplies. In this way, the gene of interest is cloned. A critical step in gene cloning is the identification of the bacterial clone carrying the gene of interest, essay on genetic engineering. Gene cloning and genetics engineering were made possible by the discovery essay on genetic engineering restriction enzymes.
These enzymes protect the bacteria against intruding DNA from other organisms, such as phages or other bacteria cells, essay on genetic engineering.
They work by cutting up the foreign DNA, a process called restriction. Most restriction enzymes are very specific, recognizing short nucleotide sequences in DNA molecules and cutting at specific points within these sequences.
The bacterial cell protects its own DNA from restriction by adding methyl Genetic engineeringalso called genetic modification, is the direct manipulation of an organism's genome using biotechnology. New DNA may be inserted in the host genome by first isolating and copying the genetic material of interest using molecular cloning methods to generate a DNA sequence, or by synthesizing the DNA, and then inserting this construct into the host organism.
Genes may be removed, or "knocked out", using a nuclease, essay on genetic engineering. Gene targeting is a different technique that useshomologous recombination to change an endogenous gene, and can be used to delete a gene, remove exons, essay on genetic engineering, add a gene, or introduce point mutations.
An organism that is generated through genetic engineering is considered to be a genetically modified organism GMO. The first GMOs were bacteria in ; GM mice were generated in Insulin-producing bacteria were commercialized in and genetically modified food has been sold since Genetic engineering techniques have been applied in numerous fields including research, agriculture, industrial biotechnology, and medicine, essay on genetic engineering.
Enzymes used in laundry detergent and medicines such as insulin and human growth hormone are now manufactured in GM cells, experimental GM cell lines and GM animals such as mice orzebrafish are being used for research purposes, and genetically modified crops have been commercialized. And whether genetic engineering can end world hunger? Keywords: geneticengineeringcrops, pros, cons, world, hunger, technology, altered, tolerated, drought Genetic engineering the deliberate modification of the characteristics of an organism by manipulating its genetic material Bensel, Genetically modified foods GM foods or GMO foods are foods derived from genetically modified organisms, GMOs.
Genetically modified organisms have had specific essay on genetic engineering introduced into their DNA by genetic engineering techniques. These techniques are much more precise than mutagenesis mutation breeding where an organism is exposed to radiation or chemicals to create a non-specific but stable change. Other techniques by which humans modify food organisms include selective breeding; plant breeding, and animal breeding, and somaclonal variation.
GM foods were first put on the market in the early s. Genetic engineering of the human food essay on genetic engineering is a highly contentious issue, with credentialed scientists arguing on each side. Most likely the controversy will continue. The effort by biotech companies to genetically modify food will continue to increase Inserting the human insulin gene into bacteria to mass produce it.
General Steps Obtain the gene of interest ex. insulin gene Insert the gene into the host ex. bacteria Allow the host to multiply and express the foreign gene get your desired protein! coli cells. coli are It has many purposes including clones, perfect humans and cures for genetic diseases, essay on genetic engineering. Gel electrophoresis is a powerful tool used for separation and analysis of macromolecules and their fragments, based on their size and charge.
You place the DNA in the gel. DNA is a long, strand-like molecule where genes are written in genetic code. Extracted enzymes recognize and extract the DNA at a specific sequence. Transgenic microorganisms are crosses between two animals or microorganisms. Scientists cross breed them. Most commonly used are genetic fruit flies to study the effects of genetic changes on development.
Flies are preferred over other other animals because their vertebrae are simpler than other organisms. Modified bacteria are used to produce the protein insulin, to treat genetic diseases like diabetes, hemophilia, and dwarfism.
Transgenic animals have had their genes altered. A majority of these animals are mice. A transgenic plant; however, has genes that have been inserted in them rather than through pollination. Benefits of these plants are that they can fight droughts, as well as insect resistance, essay on genetic engineering. Less pesticide would be used. An example of a transgenic Genetic engineering From a Christian perspective a essay on genetic engineering topic that has many ethical issues is genetic engineering.
Genetic engineering is the process by which genetic material is changed in such a way to make possible the production of new substances or new functions. In other words, it is the alteration of genetic material by direct intervention in genetic processes with the purpose of producing new substances or improving functions of existing organisms.
It is considered a young and exciting procedure. Yet it controversial type of the biological sciences. The positive uses to this procedure is that it offers some good possibilities of cures for diseases and other material improvements to daily life. However, there are negativities to genetic engineering.
It is involved in food and it contributes to the contamination of genes in crops. Genetically engineered crops may replace and be harmful for natural plants. Having unwanted genetic mutations can lead to allergies in crops and can danger nutritional value while boosting foods taste and appearance. Genetic engineering can also be a pathogen for diseases and viruses. While increasing the immunity to diseases in plants, the resistance genes may get transferred to the harmful pathogens.
Along with having a chance of Genetic engineering GE is also known, as genetic modification is the process of organisms that are genetically modified. In this process the goal is to transfer new DNA to an organism so it can improve its habits and make new cells. Genes are inserted from E. Corn, this term is known as cross breeding where different plants are modified to grow bigger plants and to produce more food.
When a gene transfer occurs, essay on genetic engineering, the gene is then called a GMO Genetically modified organismGenetic engineering is not only used on animals but its also used on many other organisms so it can improve them, such as crops or medicinal plants, bacteria and even viruses, essay on genetic engineering. Breeding is a good way of improving traits, but when they are compared with genetic engineering there can be many consequences.
Breeding also has to rely on the ability to mate two organisms to mix genes. Genetic engineering can remove genes from one organism and place them into the other. Some uses of genetic engineering include improving the nutritional quality of food, bacterial production of hormones, creating pest-resistant crops and creating livestock.
