The vector was modified to include a heterologous intron with a synthetic splice donor engineered upstream of a fragment from intron A of the gonadotropin a subunit gene(containing a splice acceptor).

载体经修改后包括带有一合成的剪接供体的一个异种内含子， 此供体经促性腺激素a亚单位基因（含有一个剪接受体）的内含子A中某片段的上游改造。

Since the split gene was found in 1977, the processing mechanism transcribed and the function of intron have been a popular subject about the study of molecular genetics ineucaryote.

自1977年发现不连续基因（断裂基因）以来，有关内元（内含子）的功用以及转录后的加工机制是真核生物分子遗传研究的一个热门。

Intron is a redundant expression for individual and attached to its algorithm tree, which makes the individual swelling but has no effect to the final output.

它们是冗余的表达式，附加在算法树上，使个体变得臃肿，但对实际的输出结果没有影响。
