How Medical Genetic Research Works
Genetic research has been used for many purposes in the medical field, including discovering new and important treatments that can lead to improving the lives of those who have certain diseases which are passed down from generation to generation in families. The basic idea of genetic research involves identifying certain mutated genes in a person's DNA and correcting them so that they do not have any issues with a weak immune system or certain diseases that they are vulnerable to because of their family's medical history.
Scientists have had varying degrees of success with medical genetic research over the years, yet some conditions still remain a mystery and do not have a cure or even an effective treatment. Sometimes a mutation can occur because a certain code gets altered. Strangely enough this is the same way that genetic research works, by altering genes that are "bad" or mutated. This requires years of research on the parts of the scientists who do this type of work every day, looking for a possible cure to many different conditions that pose a threat to millions of people all over the world.
When scientists discover that a certain condition comes about as the result of a message being deleted in the person's genetic code, their job is to put it back together in the correct order so the person is not vulnerable to these deadly medical conditions which are often genetic. Finding a treatment or cure for a single disease can take a lifetime if not more, and scientists have already been working on finding one for many conditions for a number of years.
Genetic research can be used to do other things besides just prevent and cure diseases though. Scientists are in the process of coming up with a way to choose just about everything from eye color to height in a child that hasn't even been born yet. This use of genetics certainly raises some ethical questions and it is sparking much debate in the scientific community as well as with parents of children around the world.
The ability to identify a mutated gene and correct it is a somewhat simpler task than having to do the same thing with multiple genes. One of the reasons why it takes so long to find a possible treatment or cure for a certain disease is because there are multiple genes that have been mutated, and in order to find a solution to this problem all of them must be corrected. Genetics is an extremely complex and intricate aspect of science that still has yet to be studied and we are finding out more about our own genetics each day as more and more breakthroughs take place. Now more than ever humanity is in control of its own fate, able to find cures to diseases that used to kill hundreds of thousands of people in the past. Genetics certainly plays a huge role in just about everything that makes up who we are physically, which is why it is so important to unlock all of the secrets that genes are hiding.
