Abstract
This invention relates to the field of nucleic acid chemistry, more specifically to compositions of matter that are nucleic acid analogs, and processes that use them. Still more specifically, these compositions comprise two fragments of DNA-like molecules, each having one or more ends modified to carry a reactive group, where the reactive group on one fragment can form a transient covalent bond with the reactive group on the other under conditions of dynamic equilibrium to form a composite, where the composite can then bind to a target oligonucleotide, such as a DNA or RNA molecule. Most specifically, once the transient covalent bond forms, the composite serves as a primer for a template-directed polymerization using a DNA polymerase, an RNA polymerase, or a reverse transcriptase. Once incorporated, the epimerization causes the base pair to be destabilized, the duplex containing the epimerized nucleoside to likewise be destabilized, and the double strand to then disassociate. This leaves the template available to template the synthesis of another complementary oligonucleotide containing the epimerizing base.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
