What is a GMO?

By Sourav


Genetically modified organisms (GMOs) are creatures whose DNA has been altered to alter their properties.


GMO stands for genetically modified organism.

Full Form of GMO

GM organisms are those that have undergone a modification to their genome that does not occur in nature. Altering the genetic code of an organism allows us to give it new traits.

Although it is technically possible to modify any organism genetically, laws prohibit the modification of human beings and strictly regulate the manufacture and marketing of all GMOs.

Genetically modified (GM) crops used for food and GM animals used in scientific studies are two common types of GMOs.

Creating a genetically modified organism (GMO) entails erasing or modifying certain segments of DNA to produce an organism with new properties.

How do we make GMOs?

By inserting novel DNA sequences into an organism's genome, we can alter its traits as well. This could be: DNA extracted from the same species, DNA extracted from a different species, or DNA synthesised in a lab all fit into this category.

How do we make GMOs?

The process of creating GMOs is called genetic modification or genetic engineering.

In order to alter a genome, scientists can utilise a variety of methods, including: To use a modified microorganism to transfer foreign DNA into a plant's genome, a process known as "Agrobacterium-mediated" genetic alteration is employed. Gene targeting refers to a method for inserting new DNA into specific parts of a genome via homologous recombination. The term "genome editing" refers to a process in which specific sections of a genome are altered by means of enzymes engineered to cut out only certain strands of DNA.

GMOs are generally made for medical, environmental, or commercial reasons.

Why do we make GMOs?

The gene that ordinarily causes white GM mushrooms to turn brown has been changed. The browning process in these mushrooms is slower, allowing them to be stored for longer. It has become possible to create genetically modified bacteria by inserting the gene for insulin into their DNA. The growth of these bacteria results in the production of insulin, which is then collected and used by diabetics to regulate their blood sugar levels. Psoriasis and other skin disorders may be related to mutations in the Acer1 gene. Acer1-deficient GM mice have been created so that its normal functions can be investigated. These rodents lose their hair and have impaired thermoregulation.
