ABSTRACT:
A method for determining at least one DNA sequence that can be employed as a flanking sequence to a DNA binding site for a ligand, wherein the DNA binding site is located within a preselected DNA sequence, to provide a relative increase, decrease, or approximate equality in binding constant of the ligand for its DNA binding site, or relative composite reaction rate for the ligand and a DNA sequence. Also provided are applications of the method to determine DNA primers useful in conjunction with DNA amplification to detect the presence or absence of DNA sequences and to diagnose diseases related to viral DNA, such as human immunodeficiency virus.
