[The wet weight and the content of DNA, RNA and protein of different tissues of 92 and 120 day old sheep fetuses and newborn lambs].
In sheep-fetuses of the age of 92 (615 +/- 49 g body weight) and of 120 days (1843 +/- 406 g body weight) as well as in newborn lambs (2815 +/- 648 g body weight) the content of DNA, RNA and protein per g wet weight in 14 tissues and in the fetal and the maternal portion of the placenta was analysed. A calculation of the development of the total content of DNA, RNA and protein in the different organs is given. The changes of the wet-weight:DNA-, the protein:DNA- and the RNA:DNA-ratio in the tissues during growth are described. The significance of these changes is discussed.
