The length and spacing of repetitive sequence elements were studied in several cloned sea urchin DNA fragments. Sequence organization in these fragments was found to be of the short interspersed form expected for sea urchin DNA, and for one clone the evidence shows that nearby repeats do not belong to the same repetitive sequence family.
在几个克隆的海胆DNA片段中研究了重复序列元件的长度和间距。发现这些片段中的序列组织呈海胆DNA预期的短散布形式,并且对于一个克隆,证据表明附近的重复序列不属于同一个重复序列家族。
