求翻译：事实上，低水平表达的一些mRNA起到了非常重要的生物学作用，例如转录因子和信号转导元素经常处于低水平表达，而采用DNA阵列技术对低水平转录的mRNA的检测则是不可信的。是什么意思？

In fact, low-level expression of mrna played a very important role in the biological, such as transcription factors and signal transduction elements are often at a low level expression is not credible, while the use of dna array technology to the detection of low-level transcription of mrna .

In fact, low level expression some mRNA played the extremely important biology role, for example the duplication factor and the signal extension led the element to be in the low level expression frequently, but used the DNA array technology the mRNA examination which recorded to the low-water flat t

In fact, some low expression of mRNA of biology has played a very important role, such as transcription factor expression and signal transduction elements often at low levels, using DNA Microarray for detection of low levels of transcription of mRNA is not credible.
