DNA & Genetic Testing

  • Child Brain Tumours and DNA

    Scientists from Cambridge University in the UK have found a common DNA sequence in children suffering from brain tumours. The knowledge is vital to our understanding of one of the least understood genetic disorders.

  • More Reliable Genetic Testing for Diseases

    Currently, testing for genetic disorders can only identify a very small percentage of the 15,000 known ones. However, a new test is on the horizon that has the potential to screen for nearly every kind of genetic disease.

  • What is Cushing’s Disease in Horses?

    Due to the common ancestry of all species, many diseases, (especially genetic) found in humans can be found in other organisms. For example, Cushing’s disease, an endocrine disease that affects people, can also be found in a variety of other animals, including horses.

  • Understanding RNA and RNA Alternative Splicing

    RNA alternative splicing, a common occurrence in eukaryotes, is a process by which a single gene is able to encode several different proteins. This process is instrumental in bringing about genetic diversity on the one hand and on the other it may be responsible for several genetic disorders.

  • Exhuming Jesse James for DNA

    Jesse James was still a wanted man many years after news of his death. Rumors were that he faked it. DNA testing was used to identify an exhumed body to see if it was Jesse James and silence the rumors. Find out how DNA extraction is used to prove (or disprove) the identity of a person.

  • Why Are Nematodes Used in the Laboratory?

    The fruit fly drosophila melanogaster may well be a scientist's best friend, but the nematode worm Caenorhabditis elegans runs a close second. This simple model organism can be treated like a microbe and yet it shares many genes with humans and has contributed much to the study of human physiology.

  • What is Eugenics?

    When one hears the term “eugenics”, horrid images of Nazi Germany come to mind, as well as the racist campaigns of the United States to prevent the mixing of what was at the time considered “inferior” black blood with “superior” white blood. But exactly what is eugenics? And is it still alive today?

  • What is Cushing’s Disease in Dogs?

    Cushing’s disease is an endocrine disease that affects people, but it can also be found in a variety of other animals, including dogs. The symptoms are caused by the production of too much of the hormone cortisol.
