RNA的二级结构对基因的表达有调控作用吗?

RNA secondary structure can affect the level of gene expression. For example, if the promoter and ribosome binding site of mRNA is buried by the secondary structure, transcription factors and ribosome will not be able to get access it, and thus no transcription is allowed.

If you need for detail information, type in "RNA secondary structure and gene expression" into google and read some papers.

Hope this helps:-)
