【求助】外显子剪接沉默子怎么解释？

综述要用到这个 外显子剪接沉默子 可是不知道怎么能用简单明了的词解释清楚，求助高手~多谢~

Exonic splicing enhancer (ESE)

An exonic splicing enhancer (ESE) is a DNA sequence motif consisting of 6 bases within an exon that directs, or enhances, accurate splicing of hetero-nuclear RNA (hnRNA) or pre-mRNA into messenger RNA (mRNA).

看看这篇文献Divergence of exonic splicing elements after gene duplication and the impact on gene structures。应该对你深入了解有用。知识用时方恨少，所以自己多看点多自己有用的。

可以有中文的解释吗？我还是不是很懂。
