This is a tour of different biological processes, showcasing the role of RNA. In current biology, RNA interacts with DNA and proteins to support life. The "RNA world" hypothesis states that early on in the evolution of life, DNA and proteins did not yet exist and RNA had DNA-like (genetic storage) and protein-like (metabolism, biosynthesis, etc) roles. | This is a tour of different biological processes, showcasing the role of RNA.

RNA plays key roles in gene expression, in the form of mRNA (messenger RNA), tRNA (transfer RNA) and rRNA (ribosomal RNA), the classic three types of RNA. Beyond these roles, RNA also serves to store genetic information and to regulate and modulate it. | RNA plays key roles in gene expression, in the form of mRNA (messenger RNA), tRNA (transfer RNA) and rRNA (ribosomal RNA), the classic three types of RNA.
