Inspired by a model first studied by W. Li in [7], scaling properties of the correlation function for expansion-modification systems are developed. The existence of several characteristic exponents is proved and the relationship of this fact with long-range correlations in DNA is established. Comparison between theoretical exponents and those obtained from numerical experiments and real biological sequences is also included.
