The effect of exogenous DNA on the content and rate of biosynthesis of endogenous DNA in rat bone marrow was studied. After injection of high-polymer homologous DNA into intact rats the endogenous DNA content per gram bone marrow was found to be reduced for the first 3 days (the decrease was most marked after 3 days, namely by 36%) and it returned to normal by the 6th day. The rate of DNA biosynthesis in rat bone marrow was increased after 18 h (when it was twice as high as in the control) and after 6 days (by 58%), and it was close to normal again 1–3 days after injection of DNA.(Presented by Academician of the Academy of Medical Sciences of the USSR P.
