Before revision: When exploring statistical properties of genetic sequences two main features stand out: the existence of non-random structures at various scales (e. g., long-range correlations ) and the presence of symmetries (e.g., Chargaff parity rules).
After revision: Biologists have long sought a way to explain how statistical properties of genetic sequences two main features stand out: the existence of non-random structures at various scales (e. g., long-range correlations ) and the presence of symmetries (e.g., Chargaff parity rules).
