In nuclei of hepatocytes of human embryos from the 18th to 40th week of antenatal development the activity of synthesis enzymes lowers: thymidine kinase is 7 times at low, uridine kinase - 11 times as low. In parallel during the same period a decrease in the activity of nucleases drops: DNase - by 15 times, RNase - by 11 times. The activity of these enzymes in the liver of adult persons (22-35 years old) is similar to their activity in the liver of human embryo to the moment of birth.
