Abstract
A method for preparing a ds DNA from a ss DNA template, which method includes: PA1 (a) providing a first DNA strand; PA1 (b) adding a homopolymeric oligonucleotide tail to the 3' end of the first DNA strand, to yield a tailed first DNA strand; PA1 (c) providing a ss homopolymeric oligonucleotide primer complementary to a portion of the tail; PA1 (d) contacting the primer with the tailed first DNA strand; PA1 (e) synthesizing, in the presence of the primer and the tailed first DNA strand, a second DNA strand complementary to the first DNA strand; and PA1 (f) removing the tail and the primer from the first and second DNA strands, respectively; provided that one or both of the tail and the primer contain(s) RNA.
