Imagine a world where diseases can be found and prevented before they happen. This would be a future possibility if genetic engineering became more advanced. Genetic engineering is when parts of DNA are spliced into another piece of DNA which give new traits to the organism containing the DNA. Through continued research in the field of genetics, techniques such as mapping genomes and splicing DNA can be used beneficially to improve on existing organisms and their traits.
To help understand genetic engineering, it is important to understand its history. Genetics originated when Gregor Mendel performed experiments on the genetic inheritance on plants. This was the beginning of the science of genetics and his experiments on pea plants was the basis for inherited traits. Genetics really exploded when James Watson and Francis Crick discovered the DNA molecule in 1953. This was a monumental discovery because they had discovered the shape of the molecule and also how it was structured. People were now interested if they could change or modify this structure. This eventually led to Stanley Cohen and Herbert Boyer mixing two different organisms' DNA over twenty years later. This was another huge leap in genetics because earlier it was thought that mixing different organisms' DNA to be impossible. Since these breakthroughs, the field of genetics has exploded with new research and ideas to help improve society.
Genetic engineering is crucial to improving the health of organisms through early detection or by actually changing the DNA itself. If scientists were able to map out genomes of organisms, it would help them to find and prevent diseases. If some diseases were hereditary (inherited) they could be caught early and ...

...the effects that altering of DNA will create so society needs to be careful. The advantages of genetic engineering are endless, but things like cloning and “tailor made” children are pushing the limit because they cause many moral and ethical issues. However, if society uses it to improve the lives of people it can be a very powerful tool.

Genetic engineering, sometimes called genetic modification, is the process to alter the structure and nature of genes in humans, plants, and animals (what is genetic engineering). Because DNA is a code that is universal, genes can be manipulated
With gene splicing these special scientists are on the verge of modifying certain foods to become “prefect”. Not only are we altering foods but also animals. Labs are genetically altering animals to become more adaptive to their testing need. Rats without immune systems or pigs that carry a gene for growth hormones and show significant improvement in weight gain and reduced fat. With genetic engineering we as humans could respond to diseases before they become a threat. A person’s entire gene makeup could be mapped out before they are even born. This in turn raises many controversial issues such as gene discrimination and “human perfecting”. Through the gene makeup we are able to help prevent and cure many diseases, however, life and health insurance companies could use this map to make more money off the individuals who are more likely to become sick.
Today, genetic engineering is a powerful and potentially very dangerous tool if in the wrong hands. It can completely change a product that can be very useful, or on the contrary, it is extremely harmful to the people.
The debate over whether or not the use of genetic engineering in humans is ethical has been a highly controversial topic for the past two decades. True, scientists can genetically manipulate genes in order to help cure genetic diseases, but genetic engineering can also have some undesirable consequences. Not only could genetic engineering harm humans physically, but change the way we view other humans. While the use of genetic engineering in humans can treat and cure some medical conditions, genetic engineering is a discipline that should remain unexplored.
Scientists are using various methods of genetic engineering to improve the human lifestyle. Major fields of industry are effected by genetic engineering such as the Medical, Food, Agriculture, and Environmental Industries. For example, in the Medical field, GMOs are involved in the production of insulin which can help with diabetes. In the production of vaccines, a virus’s DNA changes with the addition of extra genetic material, to help cure diseases. Also in Agriculture, by modifying a plants genetic information food yield can increase and herbicide and insect resiliency is improved. These are just a few examples of how GMOs are involved in
Although humans have altered the genomes of species for thousands of years through artificial selection and other non-scientific means, the field of genetic engineering as we now know it did not begin until 1944 when DNA was first identified as the carrier of genetic information by Oswald Avery Colin McLeod and Maclyn McCarty (Stem Cell Research). In the following decades two more important discoveries occurred, first the 1953 discovery of the structure of DNA, by Watson and Crick, and next the 1973 discovery by Cohen and Boyer of a recombinant DNA technique which allowed the successful transfer of DNA into another organism. A year later Rudolf Jaenisch created the world’s first transgenic animal by introducing foreign DNA into a mouse embryo, an experiment that would set the stage for modern genetic engineering (Stem Cell Research). The commercialization of genetic engineering began largely in 1976 wh...
Genetic Engineering is essentially altering / adding new DNA into an organism, to provide that organism with more desirable traits. Process - desired gene is isolated with restriction enzymes from organism, and then extracted. The gene then undergoes PCR (polymerase chain reaction) where the gene is sequenced and then copied multiple times, to be re - inserted into the new organism (transgenic). This process is commonly used to provide plants with more desirable traits (e.g. less reliance on water) and can be used just as easily to provide humans with the traits that they themselves desire (e.g. blonde hair and blue eyes). However, medical complications and ethical issues prevent such procedures from occurring, as the theory and practice is still very much in its infancy, and as there is no glass ceiling as such in this particular field of engineering, resulting in countless possibilities that the world may not yet be prepared for.
Shortly after the groundbreaking discovery of the structure of DNA in 1953, the scientific world was essentially given the ability to alter the genetic sequence of any living organism using a process known as 'genetic engineering'. By definition, genetic engineering is 'the deliberate modification of the characteristics of an organism by manipulating its genetic material', it is quite simply an unnatural process which defies the ordinary course of nature. As of yet, no devastating or permanent damage has been done. However, the unpredictable nature and unknown consequences genetic engineering holds is more than enough reason to be cautious, as one mistake could have irreversible and catastrophic effects.
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
Scientific advances have influenced the growth of genetic engineering by discovering new ways to fight infections. There was a gene editing tool by the name of CRISPR-Cas9 and research discovered how to improve the tool and inhibit its ability to does bad. Bacteria have developed a defense system based on DNA sequences known as CRISPR and scientists have devised the way to get past it due to genetic engineering by creating CRISPR-Cas9. And with the expansion of tools used for genetic engineering, genetic engineering can secure our future as the human race.
In the 1970's, scientists discovered that strands of DNA could be cut using special enzymes, which could cut out genetic combinations. DNA contains information about genes particular organisms hold. Duplicates of genes are also possible through genetic engineering and are very useful for medical purposes. Advances in technology have raised issues such as animal and human cloning. These issues have caused many different sided arguments.
The genetic revolution will help health professionals provide a different type of care for their patients. The genetic revolution offers enormous promises for those sufferings chronic diseases. Research laboratories around the world are busily sequencing, identifying, and switching genes among different species. Genetic engineering techniques promise cures for various diseases such as cystic fibrosis and kidney disease.
Although genetic engineering seems to be more harmful than helpful, when used correctly, it will help the society prosper. Considering the technology our society has currently developed, genetic engineering is a difficult topic to discuss and confirm. If the researchers confirm this process, it may become easier for the scientists and will help cure the diseases easily. The debate, however, will still be on the rise because of the issue in human morals and ethics.
To start with , genetic engineering is another term used for genetic manipulation which is a process consisting the addition of new DNA to an organism. The whole purpose of this process is to add new traits that are not already available in the organism. Genetic engineering is often mistaken with breeding which is technique that is mostly used with animals in order to create faster or stronger offspring. Genetic engineering is however different from breeding because it uses much less natural techniques that are usually performed in the lab. The big difference though in terms of genetics , is that genetic engineering allows gene modification that are not close to a certain species. For example , we can mix the DNA of a vegetable with the DNA of an animal in manipulation which is impossible by breeding. The basic idea of genetic manipulation is to isolate a certain cell’s DNA and to mix it with the DNA victor to create a whole new cell with new characteristics. The problem though behind all that, is that its really hard to predict what the results are going to be.
