Abstract
X-ray diffraction photographs of a nucleoprotein preparation from Escherichia coli show the A-type pattern of crystalline deoxyribonucleic acid (DNA). This suggests that a large part of the DNA is free from protein. In higher organisms DNA does not exist in this form but is closely bound to protein.
摘要
对来自大肠杆菌的核蛋白制剂进行X射线衍射拍照，结果显示出结晶脱氧核糖核酸（DNA）的A型图案。这表明大部分DNA未与蛋白质结合。在高等生物中，DNA并非以这种形式存在，而是与蛋白质紧密结合。
