A rat Alu like repetitive sequence (RALRS 1) was cloned from rat low Cot DNA library. The cloned RALRS 1 was sequenced and found to be 283 bp in length containing highly repeated AG, AGG, and AGGG sequences.

• 从大鼠低Cot值DNA文库分离到一种类Alu的重复序列 ；命名为RALRS 1.；对RALRS 1克隆并进行了测序；长度为 2 83bp；发现其中含有单一的微卫星 (microsatellite)序列AG；AGG和AGGG
