because they do not encode proteins. The involvement of noncoding mRNAs in many regulatory processes, their abundance, and their diversity of functions has led to the hypothesis that an "RNA world ...

Ribosomal RNA also performs the most crucial and ancient function inside ribosomes: the fascinatingly efficient translation of mRNA into protein. The very first proteins must have been made by ...

The rRNA molecules fold into complex secondary and tertiary structures, forming domains and motifs that are essential for ribosome function. The rRNA structures also provide binding sites for ...

The Ribosome Quality Control Complex (RQC) recognizes and destroys incomplete proteins that protrude from large ribosomal subunits that become ... The scientists don’t know the CAT tails' function yet ...

These tiny structures themselves consist of ribonucleic acid (RNA) and proteins ... function, and regulation. The production of ribosomes begins when RNA polymerase I (Pol I) synthesizes pre-rRNA, a ...
