Thermodynamics of d(GGGGCCCC) Binding to Neomycin-Class Aminoglycosides.

DNA adopts a number of conformations that can affect its binding to other macromolecules. The conformations (A, B, Z) can be sequence- and/or solution-dependent. While AT-rich DNA sequences generally adopt a Canonical B-form structure, GC-rich sequences are more promiscuous.
