对遗传信息进行编码。基因——长长的脱氧核糖核酸分子中的不连续的片段——把它们的序列转录成单线信使核糖核酸分子，核糖核酸又成为蛋白质的模板。
Genes — discrete segments of long DNA molecules — transcribe their sequences onto single-strand messenger RNA molecules, which then serve as templates for proteins.
基因组中具有调控功能的DNA序列片段可称为转录调控元件。
The DNA segments which have certain regulatory function in genomic sequences are called transcriptional regulatory elements.
对这些片段的DNA序列分析表明，它们均存在各种顺式作用元件，由此推测它们可能是被一些木质素过氧化物酶基因转录调控相关的蛋白质所结合的序列。
Analysis of the sequences showed that there were many cis-regulatory elements in these DNA segments, implying that these sequences may be bound by some transcriptional regulation protein factors.
