Process for detecting polymorphisms on the basis of nucleotide differences
First Claim
1. A process for detecting polymorphisms on the basis of nucleotide differences in random segments of nucleic acids comprising:
- (a) separately performing an extension reaction on a random segment of each of at least two nucleic acids from different sources, said reaction comprising;
(i) contacting each of the nucleic acids with at least one nonspecifically targeted oligonucleotide primer of greater than 7 nucleotides under conditions such that for at least one nucleic acid a random extension product of at least one primer is synthesized; and
(b) comparing the results of the separately performed random extension reactions for differences.

Abstract
A process is provided for detecting polymorphisms on the basis of nucleotide differences in random segments of the nucleic acid by performing a primer extension reaction on the nucleic acids and comparing the extension reaction products. The random nucleic acid segment can be amplified by first dissociating the extension product from the template and contacting the dissociated extension product with a primer under conditions such that an amplification extension product is synthesized using the dissociated extension product as a template. Differences in the extension product are useful as markers in constructing genetic maps and as markers to distinguish or identify individuals.
