ABSTRACT:
The present invention provides a DNA sequencing method comprising: (1) a step of fragmentation of a sample DNA and amplifying each fragment to obtain a first DNA fragment; (2) a step of obtaining from the first DNA fragment a second DNA fragment substantially complementary to the sample DNA at least at the 3' terminus thereof; and (3) a step of performing an extension reaction of complementary strand, using the sample DNA as a template to produce a third DNA fragment containing a base sequence complementary to the second DNA fragment and having a size longer than that of the second DNA fragment, and using the third DNA fragment as a template for sequencing of the sample DNA. DNA sequencing can be proceeded efficiently with extremely low redundancy.
