| Scientists from Portsmouth have invented a method of compressing DNA which could make gene therapy more effective. Dr John Smart, head of the School of Pharmacy at the University of Portsmouth, told BBC News Online: "DNA is a very big molecule, and there are a number of people trying to find ways of getting it into cells. "However, things that happen in cell culture may not be reproduced in humans or animals. "But if this DNA can unravel itself after being compressed, then it is promising." |
