Problems of DNA entry into a cell

This paper describes some basic processes involved when a DNA molecule face s a pore and gets through. In the simple case considered here, the only dri ving force is a concentration difference between DNA outside and inside. Fo r plausible conditions, the transfection time (the time required to force o ne molecule in) is expected to be reasonably short. (C) 1999 Elsevier Scien ce B.V. All rights reserved.
