摘要:
The present invention is directed to methods for resisting or promoting template independent nucleotide addition to the 3' terminus of a DNA duplex. The process comprises amplifying a target nucleic acid using primers which comprise a 5' terminal sequence which resists or promotes non-templated nucleotide addition to the 3' terminus of the complementary nucleic acid strand. The invention is also directed to a kit for cloning 3' nucleotidylated duplex DNA.
