Benefits and problems of genetic engineering

Transgenics refers to those specific genetic engineering processes that remove genetic material from one species of plant or animal and add it to a different species. Due to the high similarity in genetic sequences for proteins among species, transgenic organisms are able to effectively assimilate and express these trans-genes. The mule is a common example of a transgenic organism created when a horse and a donkey mate and produce offspring.

Can strawberry crops be genetically engineered to survive frost? Photo by Ken Hammond. Food can be engineered to prevent disease. Rice with built-in Vitamin A that can help prevent blindness in million children suffering from Vitamin A deficiency; A tomato that softens more slowly, allowing it to develop longer on the vine and keep longer on the shelf; Potatoes that absorb less fat when fried, changing the ever-popular french fries from junk food into a more nutritional food; Strawberry crops that can survive frost; An apple with a vaccine against a virus that causes childhood pneumonia.

These are some of the benefits promised by biotechnology. The debate over its benefits and safety, however, continues.

Do we really need to fear mutant weeds, killer tomatoes, and giant corn and will the benefits be delivered?

Cons of Genetic Engineering

Conventional breeding is a slow, unpredictable process. Desired GM organisms can be bred in one generation. Conventional Breeding versus Genetically Modified GM Crops For thousands of years farmers have used a process of selection and cross breeding to continually improve the quality of crops.

Even in nature, plants and animals selectively breed, thus ensuring the optimum gene pool for future generations.

Traditional breeding methods are slow, requiring intensive labor: In contrast, organisms acquire one specific gene or a few genes together through genetic modification, without other traits included and within a single generation.

Genetic engineering can be done with plants, animals, or bacteria and other very small organisms. Genetic engineering allows scientists to move desired genes from one plant or animal into another. Genes can also be moved from an animal to a plant or vice versa. Another name for this is genetically. Problems with Genetic Engineering Although there are many benefits of genetically engineered crops, there are also some major issues and concerns associated with these types of crops. Genetic engineering is defined as a set of technologies that are used to change the genetic makeup of cells and move the genes from one species to another to produce new organisms. The techniques used are highly sophisticated manipulations of genetic material and other biologically important chemicals.

However, this technology too is inherently unpredictable and some scientists believe it can produce potentially dangerous results unless better testing methods are developed. Traditional breeding is based on sexual reproduction between like organisms.

The transferred genes are similar to genes in the cell they join. They are conveyed in complete groups and in a fixed sequence that harmonizes with the sequence of genes in the partner cell.

In contrast, bioengineers isolate a gene from one type of organism and splice it haphazardly into the DNA of a dissimilar species, disrupting its natural sequence. Further, because the transplanted gene is foreign to its new surroundings, it cannot adequately function without a big artificial boost.

Biotechnicians achieve this unnatural boosting by taking the section of DNA that promotes gene expression in a pathogenic virus and fusing it to the gene prior to insertion.

One of the main differences between conventional and genetically modified crops is that the former involves crosses either within species or between very closely related species.

What are the Benefits of Genetic Engineering?

GM crops can have genes either from closely related species or from distant species, even bacteria and viruses. A typical example of a GM crop in the market in Australia is cotton known as Ingard. The Bt gene renders the cotton resistant to the heliothis caterpillar, a major threat to the cotton industry.

Some of the benefits of genetic engineering are as follows: 1) By using the techniques of genetic engineering, first human insulin developed for the diabetic patients. Insulin is a special component of the body and lack of this component causes diabetes. Create or edit an Event. Have an event you want to share on our website?

Benefits of Genetic Engineering WhatEngineers April 4, Genetic engineering is a stream of science where the genes of animals and all living organism are being researched, and molecular structure is formed depending on the biological effects when transferred to other living organisms.

In this example, an appropriate and selected gene in a construct containing a promoter, transcription terminator, selection marker, etc.

When combining two crops using standard agricultural techniques, genes are allowed to mix at random. A typical example is Triticale, a synthetic hybrid between wheat and rye grown in Europe, which is the result of combining 50, largely untested genes, 25, from each species.

Biotech plants are now grown on about million acres in 13 countries, including Argentina, Canada, and Germany. Economical GM supporters tell farmers that they stand to reap enormous profits from growing GM crops.

7 Advantages and Disadvantages of Genetic Engineering | Green Garage

Sustainable agriculture practices can protect the environment and produce high-quality, safe, and affordable food. Our goal is to promote such practices while eliminating harmful “factory farming” methods and strengthening government oversight of genetically engineered food.

Problems with Genetic Engineering Although there are many benefits of genetically engineered crops, there are also some major issues and concerns associated with these types of crops. The one process ongoing that will take millions of years to correct is the loss of genetic and species diversity by the destruction of natural habitats.

The first major breakthrough on the road to genetic engineering came with work done on restriction endonucleases by Herbert Boyer of the University of California at San Francisco. As defined by Karl Drlica in Understanding DNA and Gene Cloning: A Guide for the Curious, restriction endonucleases.

Genome synthesis is a natural extension of the genetic engineering tools that have been used safely within the biotechnology industry for the past 40 years and have provided significant benefits to society.
