Abstract:
Flow linear dichroism is used to measure specific inclinations for each of the four bases in poly[d(AC)].poly[d(GT)] and poly[d(AG)].poly[d(CT)] in both the B and A forms. For the B form in solution the bases are found to have a sizable inclination. Inclination is increased in the A form, as expected. In all cases the pyrimidines are more inclined than the purines.
