There is not a lot of cell-free RNA in the blood, and around 95% of it is the ribosomal RNA that makes ... molecules serve as a signal about which genes are expressed as proteins.

For example, some RNA molecules are involved in switching genes on and off ... messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). Although some RNA molecules are passive copies ...

Ribosomal RNA (rRNA) is a component of the ribosomes ... and long non-coding RNAs (lncRNAs), play essential roles in regulating gene expression. These RNA molecules can interact with mRNA, influencing ...

Regions of DNA that do not code for proteins may also be considered genes if they produce noncoding RNA with biological functions. Protein-coding versus noncoding genes When deciding the number of ...
