Experiments have been performed to test the validity of a model which relates low recovery of very early donor markers in recombinants to the presence of sex-factor deoxyribonucleic acid at the leading end of donor deoxyribonucleic acid transferred by conjugation. This model has been found to be incorrect. The results obtained do not rule out the possibility that a piece of sex factor is transferred at the leading end, but indicate, however, that if this occurs it is not the cause of the low recovery of a very early donor marker.
已经进行了实验来检验一个模型的有效性,该模型将重组体中极早期供体标记的低回收率与通过接合转移的供体脱氧核糖核酸前端存在性因子脱氧核糖核酸联系起来。现已发现该模型是不正确的。所获得的结果并不排除在前端转移一段性因子的可能性,但表明,即便发生这种情况,它也不是极早期供体标记低回收率的原因。
