Dr. Wells shared some of what he works on during the semester, and we are amazed. His students are doing some VERY interesting, exciting experiments!
As per Dr. Wells, “In the first picture, the students have taken some of their mouth cells and are isolating the DNA from those cells. In the second picture, they are using the negative charge of DNA to separate pieces of DNA based on size (using gel electrophoresis). In between the pictures they have used a technique called Polymerase Chain Reaction to make 1 billion copies of 1 small region of their DNA so we can see that not everyone has the same DNA. This has implications for DNA fingerprinting and ancestry analysis.”
This is way too cool – and VERY advanced.
