By understanding how cells work in healthy and diseased
states, cell biologists working in animal, plant and medical science
will be able to develop new vaccines, more effective medicines,
plants with improved qualities and through increased knowledge
a better understanding of how all living things live.
Eventually it will be possible to produce a 'health
forecast' by analysing your database of genetic and cell information.
Using this you will be able to take more control over your health
in a preventive way.
But cell biology is not just about disease. It has
greatly assisted the human fertility programme. DNA testing has
been used in archaeology to provide evidence that a living person
is related to a long dead ancestor.
In plant science it has been used to show that two
plants that look different have the same genetic origins.
Forensic medicine uses cell biology and DNA fingerprinting
to help solve murders and assaults. Neither the courts of law
nor the criminals can escape the importance of cell biology.
Biotechnology uses techniques and information from
cell biology to genetically modify crops to produce alternative
characteristics; to clone plants and animals; to produce and ensure
high quality food is available at lower costs; to produce purer
medicines and in time organs for the many people who need transplants.
Cell biology is about all this and can make an exciting career.
It is also important that everyone feels informed
about how the increase in knowledge about cell biology could affect
him or her and society in general. Society will have to make informed
decisions about such things as growing organs for transplanting
into humans and, in those areas where vitamin 'A' deficiency causes
blindness, growing rice modified to produce the vitamin.
A basic understanding of cell biology including
genetics will be as important as having some knowledge about computers
and the Internet.
SOMETHING TO THINK ABOUT:
If you needed a kidney transplant and no donated human organ were
available, would you refuse to have one from a pig specially developed
to provide organs for humans?
You are a rice farmer and a parent. You know that
each year more than one million children die and another 124 million
are made more susceptible to measles and diarrhoea due to shortage
of vitamin A. You have heard about a new strain of genetically
modified rice producing vitamin A is available. Would you grow
it and let your family eat it?
