Abstract:
Mammalian genomes are pervasively transcribed, with long noncoding RNAs being the most abundant fraction. Recent studies have highlighted the central role played by these transcripts in several physiological and pathological processes. Despite several metabolic features shared between coding and noncoding transcripts, these two classes of RNAs exhibit multiple differences regarding their biogenesis and processing. Here we review such distinctions, focusing on the unique features of specific long noncoding RNAs.

Types of RNA
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.
