Genetic manipulation, also called genetic engineering, refers to the alteration of the genes of an organism. It involves manually adding new DNA to an organism to add new traits. Examples of genetically engineered organisms include plants that are resistant to certain insects, plants that tolerate herbicides and crops with altered oil content.Continue Reading
Genetic engineering is performed by physically moving a gene from a donor organism into a recipient organism. It gives the organism the ability to express the trait encoded by the donated gene. Genetic manipulation involves finding an organism that naturally possesses a desired trait. The DNA is taken from the selected organism, and the desired gene is copied from the extracted genes. This is called gene cloning. It is possible to modify the gene a little in a more preferable way once it is placed inside the recipient. The next process is transformation, which involves delivering the transgene (the new gene) into the cells of the recipient organism.
A commonly used transformation technique utilizes bacteria that genetically engineer plants with DNA in a natural way. After the transgene gets inserted into the bacteria, it is delivered into the recipient’s cells. Genetic engineers do not have the capability to determine where the transgene becomes inserted in the genome, if inserted at all. Therefore, it usually takes numerous attempts to attain a few transgenic organisms. After creating a transgenic organism, genetic engineers use traditional breeding to improve the final product’s characteristics.Learn more about Molecular Biology & DNA
Genetic variation generally refers to the differences in genes between individual members of a population, or the frequency in which the various gene types are expressed. Genetic variation is incredibly important for the survival and adaptation of a species, as it helps in terms of natural selection and evolution.Full Answer >
Genetic recombination is the rearrangement of genes to produce offspring with different combinations of traits than either parent. Recombination is the source of genetic diversity in sexually reproducing organisms.Full Answer >
Genetic information is stored in several places, which are DNA molecules, genes, chromosomes, mitochondria and the genome. Different amounts and types of genetic information are stored in these locations. The majority of genetic information is stored within individual DNA molecules, although it is found in other cellular locations as well.Full Answer >
Genetic splicing is the process in which an organism's DNA is cut and another gene is added. It is used so single-celled organisms can produce certain products, such as insulin, and produces genetically altered organisms.Full Answer >
