How to Define Genetic Engineering

By Dylan Smith 29 May, 2023 3 mins read

Genetic engineering can be called many things, including genetic modification and genetic manipulation. These terms all refer to the same concept: the manipulation of genes to produce new products or organisms. There are many concerns and issues surrounding this technology. Understanding genetic engineering is essential.

Methods of genetic engineering

Genetic engineering is a process of changing genes and organisms to produce desired traits. Unintended side effects can occur. Even a single point mutation in a plant can cause it to produce wrong proteins or none at any given time, leading to hereditary disease. This is why careful research and testing are essential.

Plasmids are a common way to genetic engineer. Plasmids, which contain random DNA, can have unwanted effects on plants. A better method is the vector method, which works by inserting a specific gene into a host cell. The vector method is able to allow for genetic variation.

Applications of genetic engineering

Modern genetic engineering has made it possible to create drugs for a variety of diseases. Alefacept, which is a recombinant drug used to treat psoriasis, was licensed by Biogen, an American biotechnology company. It acts by binding to T-cells' CD2 antigen and the NK receptor to promote the autologous killing. The mechanisms behind the drug's effectiveness are still being investigated, however. The UK-based biotechnology company Polgen uses drosophila as a tool to identify genes responsible for cell cycle regulation.

The technology has also been used in agriculture. In this case, plant cells can have genetic engineering to produce extra nutrients or resist chemicals. For example, genetically modified crops can produce insecticidal proteins or be resistant to herbicides, helping farmers increase crop yields. Genetically modified plants can also be used to transmit resistance to pathogens.

Health concerns

While the potential benefits of genetic engineering for crops, animals, and human health are many, there are also significant ethical concerns regarding these methods. There are ethical concerns about genetic engineering for crops and livestock. Ethical issues have also surfaced over the potential harms of gene therapy and modifying human sperm.

Genetic engineering is a popular method of farming. However, many questions remain about its safety and effectiveness. The World Health Organization even recommends genetic engineers to avoid allergen-producing genomes. Despite widespread concern, scientists still haven't proven that GE food is harmful. The possibility of allergic reaction to GMO-modified foods is very rare. It occurs only when the genetic mutation triggers the production.

Regulation of genetically-engineered organisms

The EU Regulation on Genetically Engineered Organisms(GEOs) was originally drafted in 1998. It defines the nature, techniques and characteristics of genetically-engineered organisms (GMOs). According to the EU Directive 2001/18/EC, a GMO is any organism that has been genetically engineered. It does not include humans but can include animals, plants, or fungi that are genetically engineered. GMOs have genetic material that has been altered in order to be considered natural.

The EPA can use its broad powers to enforce GMO regulations. The EPA can set limits on the types and products that can marketed. Although it can restrict GMOs in specific fields, it might not be able to regulate them all. In other cases, regulatory agencies may decide to regulate the production, use, and disposal of GMOs if they don't provide public safety or health benefits.
