ABSTRACT:
Disclosed are oligonucleotides probes which are useful for determining a sequence of nucleotides in a target ploynucleotide. In one embodiment, the probe is of the formula: HO-(3')(B)j(5')-OP(.dbd.O-)NH-(B)k-Bt*, wherein B is a nucleotide or an analog thereof; j is in range of from 1 to 12; is in the range of from 0 to 12, such that the sum of j and k is less than or equal to 12; and Bt* is a labeled chain-terminating moiety. In s second embodiment, the probe has a formula selected from the group consisting of (1) OP(.dbd.O)(O--)O--(5.dbd.)(B)sRRRR(B)wBt*, and (2) OP(.dbd.O)(O--)(5')(B)sRRRR(B)w(3')OP(.dbd.O)(O--)O, wherein: is a deoxyribonucleotide or an analog thereof; R is a ribonucleotide; s is in the range of from 1 to 8; w is in the range of from 0 to 8, such that the sum of j and k is less than or equal to 8; and Bt* is a labeled chain-terminating moiety.
