網頁2024年4月13日 · The in vitro reconstruction of life-like self-reproducing systems is a major challenge in in vitro synthetic biology. Self-reproduction requires regeneration of all molecules involved in DNA replication, transcription, and translation. This study demonstrated the continuous DNA replication and partial regeneration of major … 網頁Step # 3. The Termination Step: Studies on the synthesis of DNA were first focussed on the elongation step, then, more recently, on the initiation step which in fact, permits the control of the process. Little is therefore known presently on the termination of replication. There … 網頁2024年4月20日 · Guanine quadruplexes (G4s) serve as regulators of replication, recombination and gene expression. G4 motifs have been recently identified in LTR retrotransposons, but their role in the retrotransposon life-cycle is yet to be understood. Therefore, we inserted G4s into the 3′UTR of Ty1his3-AI retrotransposon and measured … fanjul and associates
