WebThe ligation reaction efficiency was high with 95% yield after 4 h. In contrast, the DNA ligation occurred in only 10% under the same conditions, and only 47% yield of DNA product was detected after 24 h (Fig. 1e, f ). The observed rate constants ( kobs) were estimated as 1.4 h −1 for l - a TNA and 0.027 h −1 for DNA.
