Bacteriophage T4 was grown in the presence of labeled uridine. The deoxyribonucleic acid (DNA) of the phage was shown to contain covalently attached ribonucleotides. The label appears not to be internal in the DNA strands. Presumably, it is at the ends of the DNA strands and this may be related to DNA initiation.
噬菌体T4在标记尿苷存在的情况下生长。已表明该噬菌体的脱氧核糖核酸(DNA)含有共价连接的核糖核苷酸。标记似乎不在DNA链内部。据推测,它位于DNA链的末端,这可能与DNA起始有关。
