Nucleic acid synthesis can then be initiated by the polymerase enzyme to produce a nascent strand complementary to the first strand, thereby displacing a portion of the second strand. After halting or reducing the rate of nucleic acid synthesis, a hybridizing a hook oligonucleotide can be used hybridize to the nucleic acid through a capture region on the hook oligonucleotide that is complementary to the displaced portion of the second strand. The nucleic acid can then be isolated from the mixture of nucleic acids using the hook oligonucleotide.

Abstract: Systems, methods, and software for handling random access procedures. In one embodiment, an access network element that stores an MTC reservation pattern that defines at least one MTC-On interval where MTC is allowed, and defines at least one MTC-Off interval where MTC is prohibited. During an MTC-On interval, the access network element receives preambles for random access procedures from MTC devices, and performs the random access procedures for the MTC devices in response to the preambles. The access network element detects a transition from the MTC-On interval to a next MTC-Off interval, and determines whether the random access procedures for the MTC devices will complete before the transition. If not, the access network element modifies the MTC reservation pattern to expedite completion of the random access procedures.
