Abstract
Albino rats were given injections of sodium ribonucleate (5 mg/100 g) daily for 14 days. The intensity of P32-orthophosphate, C14-orotate, or H3-uridine incorporation in mitochondrial RNA of the liver, heart and spleen was studied. It was found that exogenous ribonucleate increases the incorporation of the labeled precursors in the total RNA, rRNA and tRNA, this increase being more pronounced in tRNA than in rRNA.
摘要
给白化大鼠每日注射核糖核酸钠（5毫克/100克），持续14天。研究了肝脏、心脏和脾脏线粒体RNA中P32 - 正磷酸盐、C14 - 乳清酸或H3 - 尿苷掺入的强度。发现外源性核糖核酸增加了标记前体在总RNA、rRNA和tRNA中的掺入，这种增加在tRNA中比在rRNA中更明显。
