Applications Of Gene Splicing
Using gene-splicing technology, vaccines have been produced. DNA from a virus can be spliced into the genome of a harmless strain of bacterial strain. When the bacteria produced the viral protein, this protein can be harvested. Since bacteria grow quickly and easily, a large amount of this protein can be extracted, purified and used as a vaccine. It is introduced into an individual by injection, which will elicit an immune response. When a person is infected with a virus by natural exposure, a rapid immune response can be initiated due to the initial innoculation. Another application of gene spicing technology is related to the gene involved in Vitamin B production. This gene has been removed from a carrots genome and spliced into the genome of rice. The genetically engineered recombinant rice strain therefore, is modified to produce Vitamin B. This can have many health-related benefits, particularly in third world countries that rely on rice as a major food source and do not have access to food sources rich in vitamins.
Gene splicing technology, therefore, allows researchers to insert new genes into the existing genetic material of an organisms genome so that entire traits, from disease resistance to vitamins, and can be copied from one organism and transferred another.
