... action of two enzymes (thymidylate synthase - Tsase and dihydrofolate reductase - DHFR) is essential for DNA synthesis in all organisms. Then, in 2002, Ursula Liebl and Hannu Myllykallio from Ecole ...

"By analyzing individuals born at different times before 1955, it is possible to establish the age up to which DNA synthesis occurs, or whether it continues beyond that age," Buchholz said.
