New roles for RNAs in biology continue to emerge, and a glance at the history of RNAs may
prepare molecular biologists for future discoveries about these powerful molecules. A …

RNA plays a central, and until recently, somewhat underestimated role in the genetics
underlying all forms of life on earth. This versatile molecule not only plays a crucial part in …

Technological advances over the past decade have unraveled the remarkable complexity of
RNA. The identification of small peptides encoded by long non-coding RNAs (lncRNAs) as …

In addition to mRNA, rRNA and tRNA, which play central roles within cells, there are a
number of regulatory, non-coding RNAs (ncRNAs). Of varying lengths, ncRNAs have no …

Discoveries over the past decade portend a paradigm shift in molecular biology. Evidence
suggests that RNA is not only functional as a messenger between DNA and protein but also …

The origin story and emergence of molecular biology is muddled. The early triumphs in
bacterial genetics and the complexity of animal and plant genomes complicate an intricate …

A variety of RNA molecules have been found over the last 20 years to have a remarkable
range of functions beyond the well-known roles of messenger, ribosomal and transfer RNAs …

The ability to sequence genomes and characterize their products has begun to reveal the
central role for regulatory RNAs in biology, especially in complex organisms. It is now …
