DNA manipulation is one of the sensational topic that exist in our contemporary society. Manipulating DNA basically means changing the forms or the structure DNA of certain thing to change the traits genetically. Some people believe that manipulating DNA have multiple risks. However, I firmly believe that there are relatively more benefits than dangers, and I am going to inform about those benefits. First, changing DNA could stop the problem of famine. As the technology thrived, the population rates around countries are increasing rapidly. When there are increasing numbers of population, the foods or resources that people consume are starting to become scarce due to the limited amount. However, by changing DNA, we could grow more foods at a faster rate. For example, if we change the DNA of corn to make it sustainable at the cold …show more content…
And if those manipulation is successful, then the price of food will decrease, and it will obviously give benefits to poor’s. Increasing a number of certain livings things also can be done on animals. For example, if the numbers or prosperity of lions are scarce due to its weakness, scientist could insert DNA that makes them stronger.
DNA manipulation could also impact on medical subjects. One of the best medical outcome would be the prevention of deformed children. If scientists spots a deformed DNA in certain baby, they could replace the deformed DNA with the healthy one before it gets born. And by changing the DNA manipulation, we could prevent the spread of diseases. As time goes by, bacteria evolves, they adapt to the new medical treatments. However, if we could change those subjects, we could prevent the spread of disease. And also, we could change parent’s DNA to change their baby’s outlook, or physical appearances. If the development of DNA

The age of genetic technology has arrived. Thanks to genetic technological advancements, medical practitioners, with the help of genetic profiling, will be able to better diagnose patients and design individual tailored treatments; doctors will be able to discern which medications and treatments will be most beneficial and produce the fewest adverse side effects. Rationally designed vaccines have been created to provide optimal protection against infections. Food scientists have hopes of genetically altering crops to increase food production, and therefore mitigate global hunger. Law enforcement officers find that their job is made easier through the advancement of forensics; forensics is yet another contribution of genetic technology. Doctors have the ability to identify “high-risk” babies before they are born, which enables them to be better prepared in the delivery room. Additionally, oncologists are able to improve survival rates of cancer patients by administering genetically engineered changes in malignant tumors; these changes result in an increased immune response by the individual. With more than fifty years of research, and billions of dollars, scientists have uncovered methods to improve and prolong human life and the possibilities offered by gene therapy and genetic technology are increasing daily.
DNA is continuously evolving as it has developed various aspects of illicit cases, as well as playing vital roles in all cellular systems. The discovery of DNA has impacted and will trigger the fuel of new findings later in the future. DNA does not only significantly affect a cell’s function, but it aids the species to develop and reproduce, despite the altering conditions.
Human manipulation of DNA, also known as genetic engineering and recombinant DNA technology, is a process that involves combining DNA, and inserting the newly recombined DNA into cells to be expressed through protein synthesis. The human manipulation of DNA can be beneficial and disadvantageous. It allows genetically engineered (GE) proteins to be manufactured, aiding those with cardiac issues, and can increase genetic diversity. Contrarily, it can decrease biodiversity, and create unknown conditions. Currently, genetic engineering can be used on crops, human proteins, and plants, raising the question, “Will the human manipulation of DNA provide significant benefits to today’s society?”
Within the last 100 years or so scientists have many valuable discoveries that have benefited mankind. These discoveries include the discovery of genes. Scientists have discovered what makes humans so unique from one another. However, with this newly gained knowledge of the function of genes comes the ability to alter or change them. Just imagine in the not so near future, you and your partner want to start a family together. You travel to your local gene councillor to pick the physical and characteristic traits of your child. That’s right. With the knowledge that has been gained about genes, scientists can “create” the perfect child genetically. The thought is scary. Nature has always taken us down the right path but are we really ready to take control? Do we really know enough? Can we handle the consequences?
From genetic engineering scientist were able to come with a reproductive medicine to help women who could not have kids, conceive and bear children(Designer baies,para.1).Genetic engineering could also help wipe out some of the most serve diseases among babies. For instant, Cystic Fibrosis is a deadly disease with no cure but through genetic engineering it can be cured (Pros and Cons of Genetic Engineering,par.1). Using genetic engineering for this purpose allow for babies to be healthy and strong, which is more important than the looks of the child.This also allows for not only more babies, but for them to live longer by curing
Genetic engineering depends on the location and analysis of genes on chromosomes and ultimately DNA sequencing. The early cartography of the genes used the principles of Mendelian genetics . It is assumed that alleles that are transmitted together side by side are located on the same chromosome : it is said that are connected or linkage . These genes form a bridging group - linkage group : are the same for gametes and are usually transmitted together , so they do not have independent distribution. Crossing-over occurring during meiosis may cause these alleles can be exchanged between the chromosomes of a homologous pair .
Gene therapy focuses on the replacement of defective genes with modified functioning genes. Many diseases are caused by a defective gene meaning the body is incapable of producing essential proteins or enzymes. In its simplest form, gene therapy aims to identify the defective gene and fix this gene with the replacement of a normal gene (Senn).
2). As a result, this scientific experiment changed the relationship of humankind and nature by foreseeing the modification of DNA of bacteria, yeast, plants, and animals to discover new medicines and to provide solutions for inherited diseases (Le Vine, 1999, p. 2).
Over the past few decades, advances in technology have allowed scientists to actively manipulate the genetic sequence of an organism through a process called 'genetic engineering'. Many believe that this is a technique which we should exploit and take full advantage of as, after all, it may be the key to curing many hereditary diseases such as heart disease and cancer. It may very well be the solution to overcoming evolutionary barriers and allow us to breed new species. However, if you consider the unknown consequences we may have to face as a result of our futile experimenting, you would find that messing with a system as intricate as nature for curiosity's sake is hardly justifiable.
Is genetic engineering right or wrong? To answer these questions we need to define genetic engineering. It is the use of biotechnology to control the genes of an organism. Genetic engineering isn’t new. It has been with us for centuries. In those days, we used it for agriculture and selective breeding of animals. Our pets, especially dogs and cats are good example of selective breeding.
Genetic Engineering is the deliberate alteration of an organism's genetic information (Lee 1). The outcome scientists refer to as successful entitles the living thing’s ability to produce new substances or perform new functions (Lee 1). In the early 1970’s, direct manipulation of the genetic material deoxyribonucleic acid (DNA) became possible and led to the rapid advancement of modern biotechnology (Lee 1).
Another area of medical advancement is genetic engineering. Genetic engineering will detect and possibly stop diseases before birth. Many diseases are associated with specific genes that can be checked for disease and replaced if dysfunctional. Genetic testing has already revealed genetic mutations that cause hypertension, heart disease, diabetes, osteoporosis, colon cancer, polycystic kidney disease, Alzheimers disease, and others. (5) Replacing missing, altered, inactive, or dysfunctional genes will prevent diseases or even death. Also, progression of a disease can be monitored, and
Genetically modified organisms can be plants or animals that have been genetically altered to produce or express a desired characteristic or trait. By genetically altering organisms such as crops, we can eliminate the use of pesticides by making the crops resistant to insects. We can also produce crops that are resistant to floods and droughts. Furthermore, with the use of molecular genetics, we are able to produce foods that are rich in nutrients and supplements. People in developing countries may not be fortunate enough to have a full course meal that contains nutrients from all four basic food groups. However, GMOs can with a little modification provide all the amino acids, vitamins, and minerals included in a good diet by simply consuming a genetically modified staple crop such as rice. In addition, by producing crops that are resistant to harsh environmental conditions as well as pests, we would see a rapid increase in the production of food thereby reducing and or!
Human genetic engineering can provide humanity with the capability to construct “designer babies” as well as cure multiple hereditary diseases. This can be accomplished by changing a human’s genotype to produce a desired phenotype. The outcome could cure both birth defects and hereditary diseases such as cancer and AIDS. Human genetic engineering can also allow mankind to permanently remove a mutated gene through embryo screening, as well as allow parents to choose the desired traits for their children. Negative outcomes of this technology may include the transmission of harmful diseases and the production of genetic mutations.
