Next, the scientists heated the dissimilar DNA molecules, causing each double helix to unwind and separate into one lighter and one heavier strand. Taking only the heavier strand from each virus, the researchers placed them in the same test tube, reheated them and then cooled them slowly, a process that causes two chemically complementary strands of DNA to combine...
Now that they can experiment with a single gene, scientists may well learn how it orders the cell to produce vital proteins, and what substances cause the gene to "turn on" or "turn off." Ultimately, this could lead to the repair or replacement of defective genes and the cure of...
