what is a genetically modified organism (gmo) course hero

GMO (short for “genetically modified organism”) is a plant, animal or microbe in which one or more changes have been made to the genome, typically using high-tech genetic engineering, in an attempt to alter the characteristics of an organism. Genes can be introduced, enhanced or deleted within a species, across species or even across kingdoms.

Full Answer

What is a GMO?

A genetically modified organism (GMO) is an organism whose DNA has been modified in the laboratory in order to favour the expression of desired physiological traits or the production of desired biological products.

What is the difference between the two types of GMOs?

Generally, based on the origin of the DNA piece, there are two types of GMOs. They are cisgenic and transgenic GMOs. Basically, GMO is cisgenic when the foreign DNA piece belongs to the same species while it is transgenic when the foreign DNA piece belongs to a different species.

How do GMOs help the environment?

GMO crops that are tolerant to herbicides help farmers control weeds without damaging the crops. When farmers use these herbicide-tolerant crops they do not need to till the soil, which they normally do to get rid of weeds. This no-till planting helps to maintain soil health and lower fuel and labor use.

Research indicates that GM crop technology can result in a net increase in herbicide use and can foster the growth of herbicide resistant weeds. In addition, there is concern that the use of GM crops may negatively impact the agriculture ecosystem.

What is the process of GMO?

GM is a technology that involves inserting DNA into the genome of an organism. To produce a GM plant, new DNA is transferred into plant cells. Usually, the cells are then grown in tissue culture where they develop into plants. The seeds produced by these plants will inherit the new DNA.

How are GMOs made?

Genetically modified organisms (GMOs) are produced using scientific methods that include recombinant DNA technologyand reproductive cloning. In reproductive cloning, a nucleusis extracted from a cell of the individual to be cloned and is inserted into the enucleated cytoplasmof a host egg(an enucleated egg is an egg cell that has had its own nucleus removed). The process results in the generation of an offspring that is genetically identical to the donor individual. The first animalproduced by means of this cloning technique with a nucleus from an adult donor cell (as opposed to a donor embryo) was a sheep named Dolly, born in 1996. Since then a number of other animals, including pigs, horses, and dogs, have been generated by reproductive cloning technology. Recombinant DNA technology, on the other hand, involves the insertion of one or more individual genes from an organism of one species into the DNA(deoxyribonucleic acid) of another. Whole-genome replacement, involving the transplantation of one bacterialgenome into the “cell body,” or cytoplasm, of another microorganism, has been reported, although this technology is still limited to basic scientific applications.

Why are GMOs important?

What is an organism in GMOs?

Why are GMOs important?

In the future, GMOs are likely to continue playing an important role in biomedical research. GMO foods may provide better nutrition and perhaps even be engineered to contain medicinal compounds to enhance human health. If GMOs can be shown to be both safe and healthful, consumer resistance to these products will most likely diminish.

What are GMOs used for?

Most animals that are GMOs are produced for use in laboratory research. These animals are used as “models” to study the function of specific genes and, typically, how the genes relate to health and disease. Some GMO animals, however, are produced for human consumption.

How can we modify plants and animals?

Conventional methods of modifying plants and animals— selective breeding and crossbreeding —can take a long time. Moreover, selective breeding and crossbreeding often produce mixed results, with unwanted traits appearing alongside desired characteristics. The specific targeted modification of DNA using biotechnology has allowed scientists to avoid this problem and improve the genetic makeup of an organism without unwanted characteristics tagging along.
