Abstract
We find that in the circular extrachromosomal DNA from Drosophila tissue culture cells the transposable elements copia, 412, 297, and mdg 1 are present in variable amounts. There is no detectable circular DNA homologous to B104 . From the relationship between the intra- and extrachromosomal forms it appears that the amount of different circular elements is not related to the amount of the respective chromosomal elements.
摘要
我们发现，在果蝇组织培养细胞的环状染色体外DNA中，转座因子copia、412、297和mdg 1的含量各不相同。未检测到与B104同源的环状DNA。从染色体内和染色体外形式之间的关系来看，不同环状元件的数量似乎与各自染色体元件的数量无关。
