Abstract

Proteins that mimic DNA present a surface that is similar in shape and chemical character to the DNA double helix. These DNA mimics bind to DNA‐binding proteins, taking the place of DNA. Natural DNA mimics play roles in genetic regulation and defense. Copyright © 2005 John Wiley & Sons, Ltd.
