==RNA structure and function==

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 tour of different biological processes showcases the role of RNA. In many of these roles, RNA interacts with DNA and proteins to support life. Early on in the evolution of life, according to the "RNA world" hypothesis, DNA and proteins did not yet exist and RNA had DNA-like roles (genetic storage) and protein-like roles (metabolism, biosynthesis, etc), some of which it retains to the present day.

===Genetic information===

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. The classic three types of RNA are mRNA (messenger RNA), tRNA (transfer RNA) and rRNA (ribosomal RNA), all of which have a crucial role in gene expression. Beyond these roles, RNA also serves to store genetic information, to regulate gene expression and to modulate the sequences of protein through alternate splicing.
