Analysis of the content of DNA, RNA, and protein in different tissues of fallow deer (Dama dama L.) of various ages

The contents of DNA, RNA, and protein of 13 tissues was analyzed for 4 one day old male deer, each of 3 male deer ranging in age between 15 and 27 mon ths, for 3 experimentally induced cryptorchids (short scrotum stags) 15 mon ths of age,and for 4 castrated 27 month old deer. At the age of one day the content of DNA per g fresh weight was highest in the lung and in the splee n, and lowest in the cerebrum. The DNA content in most tissues (with except ion of the thymus) of deer between the ages of 15 and 27 months was lower t han in the newborn animals. Among animals of all ages the highest RNA conte nt per g fresh weight existed in the pancreas and the liver. The highest fr esh weight: DNA-relation was determined for the cerebrum, the brain stem, t he heart and the pancreas, while the lowest were in the lung and in the spl een. The highest RNA:DNA relation was always found in the pancreas and the lowest in the lung and spleen.
