Genetic engineering, also called genetic modification, is the technology of human manipulation of an organism's genetic material in a way that does not occur under natural conditions. Since human can manipulate the DNA, various kinds of benefits or advantages have been showed. Here are some of the uses of DNA in technology
- Diagnosis of diseases - Scientists are able to clone the entire DNA molecule that is associated with various kinds of diseases. Hence, it is possible to determine individuals that carrying certain diseases even they show no signs or symptoms of that particular disease.
- Human gene therapy - For any patient with genetic disorder that traceable to a defective allele, it is possible to replace that particular defective allele with a fuctional and normal allelel by using DNA recombinant.
- Environmental use - With the using of DNA in technology, microorganisms are able to cope with various environmental problems in terms of they can transform chemicals like having the ability to extract heavy metals under the soil for example copper and lead.
