How can genetic engineering be used to treat monogenic disorders?
Genetic engineering can be employed to treat the monogenic disorders in which there is a mutated gene causing the disease. Many such studies are being carried out, and several alternative strategies have been proposed. One such disease is Amyloid transthyretin (ATTR) amyloidosis, which occurs as a result of a mutation in the TTR gene and leads to amyloid protein build up in the nerves connecting the spinal cord and brain. Research is going on to utilize the CRISPR technology to knock-out the mutated gene responsible for this. This involves gene deactivation or deletion of a gene sequence [8].

What are genetic engineers doing?
Genetic engineers have turned into modern-day alchemists, who are searching for the ultimate elixir of life, to produce the genetically modified, perfect human. This precious knowledge is being exploited by greedy men, who are using it just to earn more money. Nothing is bad if exploited within limits.
How does genetic engineering affect humans?
Genetic engineering can hamper the genetic diversity in humans if all the defective genes were replaced by functional genes. In such a scenario, all humans will have a similar genetic makeup, and therefore, a new and unknown virus or a disease may affect a much larger population of humans.
What are the disadvantages of genetic engineering?
Disadvantages of Human Genetic Engineering 1 Man has yet to understand the complexities of nature and how human life is connected and inter-woven with other components of nature. Some scientists are of the opinion that genetic engineering in humans might have destructive results, that may be irreversible. 2 Genetic engineering can hamper the genetic diversity in humans if all the defective genes were replaced by functional genes. In such a scenario, all humans will have a similar genetic makeup, and therefore, a new and unknown virus or a disease may affect a much larger population of humans.
Why was genetic engineering applied to plants?
It was applied to plants in order to produce genetically modified foods, with higher resistance to infections and high nutritional values. With the advancement in technologies and major breakthroughs in genetic engineering, more and more scientists are experimenting with human genes.
What is the DNA of a person?
The tiny, microscopic DNA contained all the genetic information related to the person, like color of the eyes, hair, skin tone, height, weight, IQ, EQ, diseases, disorders, etc., and was even able to determine a smile or the shape of one’s nose. This blueprint of life is the most important ingredient of genetic engineering.
Why are better drugs produced?
Better drugs could be produced that are disease- or gene-specific, and attack the specific genetic mutation in an individual, to help overcome a disease or disorder.
When was genetic engineering invented?
The term genetic engineering was first used in Dragon’s Island, a science fiction novel by Jack Williamson in 1951. With the discovery of ‘deoxyribonucleic acid’ or mitochondrial DNA by James Watson and Francis Crick, this fictional plot started to turn into a reality. Watson and Crick, with their experiments, could prove ...
What is genetic engineering?
To me, genetic engineering, broadly defined, means that you are taking pieces of DNA and combining them with other pieces of DNA. [This] doesn't really happen in nature, but is something that you engineer in your own laboratory and test tubes.
When was genetic engineering invented?
Genetic engineering is a term that was first introduced into our language in the 1970s to describe the emerging field of recombinant DNA technology and some of the things that were going on.
How do humans manipulate their genomes?
Traditionally, humans have manipulated genomes indirectly by controlling breeding and selecting offspring with desired traits. Genetic engineering involves the direct manipulation of one or more genes. Most often, a gene from another species is added to an organism's genome to give it a desired phenotype.
What are the benefits of genetic engineering?
Another benefit of genetic engineering is the creation pharmaceutical products that are superior to their predecessors.
What is gene therapy?
Gene therapy is the medical treatment of a disease by repairing or replacing defective genes or introducing therapeutic genes to fight the disease. Over the past ten years, certain autoimmune diseases and heart disease have been treated with gene therapy.
Can genetic engineering cure ALS?
The hope is that soon, through genetic engineering, a cure can be found for these diseases by either inserting a corrected gene, modifying the defective gene , or even performing genetic surgery.
Why is genetic engineering important?
Pros: – As indicated above, genetic engineering is meant to eliminate flaws in humanity’s genetic makeup. Consequently, those children that were genetically modified before birth will probably emerge healthier on average than a normal baby. Geneticists will be able to target specific genetic defects and get rid of them before the child ages.
How does genetic engineering help us live longer?
– Genetic engineering can potentially eliminate the age barrier, and allow humans to live a great deal longer.

For others, it’s an abomination: a method ...
Can the wealthy afford gene therapy?
It’s likely that only the wealthy will be able to afford gene therapy, at least at first, and the resulting ‘improved’ humans could be seen as a species above the rest, or perhaps even perceive themselves as such. This could result in some fairly radical class wars, and a great deal of resentment.
Positives of Genetic Engineering
Most people tend to focus on the negatives of genetic engineering, but there are some substantial positive we need to consider as well. Genetic engineering is a debate, and there are some good points on each side. You have to look at both the pros and cons of genetic engineering if you want to make an informed decision on the matter.
Negatives of Genetic Engineering
Of course, genetic engineering isn’t entirely positive. There is an upside to the ability to genetically alter humans and animals, but only in ideal situations.
