The first type of DNA testing used for Genealogical research was the Mitochondrial DNA. Mitochondrial is found in organelles found in the cell nucleus. Mitochondrial was discovered as having it's own DNA make up in 1963, though public testing didn't begin until the 1990s.
With DNA, you have to be able to tell which genes are turned on or off. Current DNA sequencing cannot do that. The next generation of DNA sequencing needs to be able to do this. If somebody invents this, then we can start to very precisely identify cures for diseases. It will be a really huge advancement for humanity.
We’ll be able to design treatments specifically for individual people and be able to tell beforehand if certain treatments would result in negative side effects for certain individuals.
The race is on, and some companies are doing a better job of DNA sequencing. It could be said that the the companies that will win the race to the answers will be the companies that inspire and support innovation. With the innovative advancements, new discoveries such as genes that identify frailties to cancer and other diseases will happen. All these advancements are kept in close confinement from the competition. Rumors of advancements raise stock prices and give hope to many hanging onto life with genetic cures in their dreams.
