Line 34:

Only a small fraction of the human genome codes for proteins, tRNA or rRNA. The remainder has been called "junk DNA" in the past, but some of it codes for RNA that plays a role in gene regulation.

====Riboswitches====

Riboswitches work by binding to segments of RNA, thereby changing the structure of it (for example, by competing with an interaction supporting one structure, they allow it to fold into a different structure. The structure of the riboswitches is sometimes dependent on binding to small molecules, like the <scene name='49/491851/Riboswitch/1'>riboswitch bound to S-adenosylmethionine shown here</scene>.
