The intramolecular thermolysis of organic compounds with an unsaturated functional group involving the transfer of a 纬-hydrogen to the unsaturated center via a six-membered transition state to yield both ene and enophil is generally known as the retro -ene reaction or retro -ene fragmentation. ...

5A), indicating that in vitro completion of RT reaction in cRTCs increased their ability to integrate into chromatin. ERT did not increase the integrative capacity of nRTCs isolated at 5 h post-infection (Fig. 5B), although the low rate of ERT was observed in these complexes (Fig. 5A)....
During the reverse transcription reaction, NC functions in an important role of preventing the self-annealing and -priming of cTAR DNA. This facilitates the synthesis of a proper DNA intermediate at the first-strand transfer step of the reverse transcription. Therefore, we examined the effects of ...
