Final goal of biotechnology
The final goal of advances in biotechnology is for the
benefit of mankind. Biotechnology largely contributes to human genetic research
involving the following areas
Ø Genetic
testing and screening for diseases
Ø Genetic
portifolios
Ø Human
gene therapy
Genetic testing and screening
Genetic techniques are now available for prenatal testing
to specifically detect whether a fetus carries genetic defects. This will help
the parents to be better prepared for the future baby. The negative aspect of
prenatal testing is that the couple may opt for abortion even for a minor
genetic defected or sometimes for gender bias.
Genetic portifolios
The elucidation of the entire human genome sequence and
identification of genes has now become a reality. It may soon be possible to
have individual genetic portifolios that will diagnose future health complications for
example risk for cancer,
heart disease.
The genetic portifolios will fortell the individual’s future, which is now
being predicated through stars.
Genetic portifolios of individual may pose certain
problems with regard to marriages, insurances. Who would like to be a spouse of
someone who will soon be a victim of cancer or heart
attack, which insurance
company would insure person with a very high risk for cancer and heart
diseases, many ethical committees are of the opinion that insurance companies
should not require, or should not be allowed to have access to individual’s
genetic portifolios.
Human gene therapy
There are two approaches to achieve gene therapy, they are
Ø Somatic
cell gene therapy
Ø Germ
cell gene therapy
Somatic cell gene therapy
The non-reproductive cells of an organism are referred to
as somatic cells. These are the cells of an organism other than sperm or eggs
cells, bone marrow cells, blood cells, and skin cells, intestinal cells. At
present, all the research on gene therapy is directed to correct the genetic
defects in somatic cells. The somatic cell gene therapy involves the insertion
of a fully functional and expressible gene into a target somatic cell to
correct a genetic disease permanently.
Germ cell gene therapy
This is not being carried out at present due to technical,
ethical and social reasons. Manipulation of germ cells will lead to serious
problems and complications. At one international meeting on biotechnology the
following was the final message given to biotechnology companies on the
application of genetic engineering to humans.
