DNA analyzing method.

摘要

A DNA analyzing method which bonds the oligomer of the known base sequence to the DNA fragment obtained by digesting sample 1 with restrictive enzyme, causes hybridization between oligomer 3 and DNA fragment using the oligomers 3 which have the sequences of all combinations of the types of the bases within the length of several bases following the known base sequence, checks presence or absence of the hybridization or complementary DNA strand extension, identifies the DNA fragment terminal sequence from this result, and fractionates the DNA fragments and analyzes them or analyzes them as they are. This DNA analyzing method provides an effective analysis of mixtures of long DNAs or DNA fragments.
