再发生的

The prospect of graft loss is a problem faced by all transplant recipients, and retransplantation is often an option when loss occurs.

移物失功的远景在所有移受体面前的一个问题，当发生的时候再移通常一个选择。

However, this technique continues to be characterized by its propensity to elicit passive results, such as restenosis,inflammation, thrombopoiesis, formation of encrustation or stone.

但,再狭窄、感染、凝血、硬壳或者结石的形成仍然容易发生的问题。

Alternatively, a new version of a gene can also be created through reverse transcription: during gene expression, the mRNA is copied back into a sequence of DNA that is inserted into the genome.

其二，新的基因复本也可能透过反转录作用，将基因表现出来的mRNA反转录成DNA序列，再插回基因组内，这种现象称为反转录移位（retrotransposition），发生在细胞内称为长散布核因子（LINE）的转位子活动时。
