DNA prefers to dive head first into nanopores
Providence RI (SPX) Jan 10, 2013
If you want to understand a novel, it helps to start from the beginning rather than trying to pick up the plot from somewhere in the middle. The same goes for analyzing a strand of DNA. The best way to make sense of it is to look at it head to tail. Luckily, according to a new study by physicists at Brown University, DNA molecules have a convenient tendency to cooperate. The research, published in the journal Physical Review Letters, looks at the dynamics of how DNA molecules are captured by ... read more
