1442 Words6 Pages

DNA was the only thing that contributed to a little girl's death one friday night, when she collapsed from a heart attack suddenly.

Certain mutations and differences can transpire in someone's genes which causes particular genetic diseases and variances to occur. By taking samples of a person's DNA, which is what our genes consist of, doctors can determine mutations in genes that can impact specific traits and illnesses. While this is very intriguing to me, I wanted to understand how accurate genetic testing is, and how it affects people's everyday lives. My search consists of uncovering more about genetic testing itself at its core, and will include how much these tests cost, what companies provide answers to discovering what lays in our …show more content…

As I was watching the documentary Cracking your Genetic Code, they discussed how genetic diseases can be very hard to diagnose if that alteration in a person's genes has not yet been found in previous patients. By analyzing many different people, doctors were able to find the breast cancer mutation. For example, this would have not been able to occur without testing patients and finding certain similar alterations in different DNA samples. It is also how they discovered that seventeen genes lead to colon cancer (Weintraub Arlene). There are still many undiagnosed variations of genes out there, and genetic testing could help find more answers concerning

    I agree. In some cases, knowing that you have a mutation and will be affected with the disease could be very emotional for an individual. One never knows how they will respond to the result and pretesting counseling may not fully prepare the individual for the result. One question that has been raised is should genetic counseling be allowed for diseases that are not treatable? It is thought that if an individual knows they will develop a condition that has no treatment it could cause psychological harm, stigmatization, and possible discrimination.

I argue that animal testing is wasteful because it prolongs the suffering of humans waiting for results of misleading experiments. Not all tests done to animals apply to humans, for our genetic makeup and composition differ from each other.
