General description
Poly(deoxyguanylic-deoxycytidylic) acid (poly(dG-dC)) undergoes salt dependent conformational transition. Under high-salt, it exists as a left-handed double helix and at low-salt it displays B-DNA conformation. However on immobilization, poly(dG-dC) takes up A DNA form.
Application
Poly(deoxyguanylic-deoxycytidylic) acid (Poly(dG-dC) • Poly(dG-dC)) is an alternating copolymer, self-complementary, double-stranded DNA model for conformational studies of DNA structure dynamics and drug interaction.
Poly(deoxyguanylic-deoxycytidylic) acid sodium salt has been used:
- in electrophoretic mobility shift assay of transcription factor IIIB complex
- as synthetic copolymers for circular dichroism (CD) spectroscopy studies
- as a positive control in liquid scintillation counting
Other Notes
Alternating copolymer; self-complementary, form double-stranded complex

Ultraviolet light is strongly absorbed by DNA, producing excited electronic states that sometimes initiate damaging photochemical reactions. Fully mapping the reactive and nonreactive decay pathways available to excited electronic states in DNA is a decades-old quest. Progress toward this goal
