 | | Start / S / Science News / August 10, 1991 / A 3-D image reveals a steroid-gene link. |
 | | In the Aug. 8 Nature, Paul B. Sigler of Yale University and his co-workers show how a gene fragment binds to the part of a steroid receptor that recognizes specific DNA sequences. |
 | | Their three-dimensional, computer-generated image, based on X-ray crystallography, reveals that it is not only the binding between DNA and the steroid-receptor molecule, but also the spacing between binding regions, that tells these gene-activating molecules when they've latched onto the right gene. |
