Method of synthesizing double-stranded DNA molecules

Patent ·
OSTI ID:7147415
This invention relates to a method in which the polymerase chain reaction (PCR) is used to generate products that when combined, denatured, and reannealed, form double-stranded DNA with discrete, cohesive, single-stranded ends. Such cohesive ends can be utilized in the formation of precise, directional DNA joints without dependence on enzyme-restriction sites. Furthermore, the placement of cohesive single strands on both ends of a DNA molecule permits a DNA strand or strands to be annealed to form circular DNA. These recombinant circles of DNA can be directly transfected into appropriate host cells. The method of generating recombinant circles upon reannealing PCR generated products simplifies DNA mutagenesis, recombination, and cloning.
