How these "adult-born" cells build their connections with the rest of the brain, and the extent to which they resemble...... Many chain molecules are able to adopt a suitable spatial structure, but only a few bases can enter into the necessary specific pairing. In this, our alternative bases are clearly inferior to the usual WatsonCrick bases.
