A non-coding RNA (ncRNA) is a functional RNA molecule that is not translated into a protein. The DNA sequence from which a functional non-coding RNA is transcribed is often called an RNA gene.

Jan 3, 2023 · This Consensus Statement addresses the definition, nomenclature and classification of long non-coding RNAs, and provides a shared viewpoint on their features and functions.

Non-coding RNAs (ncRNA) are transcribed from DNA but do not translate into proteins. They play crucial roles in regulating gene expression at both the transcriptional and post-transcriptional levels 1.

The non-coding RNAs are classified into various types depending on their size, processing, and function and include tRNAs, rRNAs, microRNAs, small snoRNAs, snRNAs, PIWI-interacting RNAs, and the …

In this chapter, we will introduce several classes of short and long non-coding RNAs, describe their diverse roles in mammalian gene regulation and give examples for known modes of action.

Nov 14, 2024 · Non-coding RNAs (ncRNAs) are transcriptional outputs that do not translate into proteins, with a spectrum of diversified biogenesis, size, shape, and function.

Jul 30, 2025 · Non-coding RNAs constitute approximately 80% of the cell’s total RNA by mass, whereas coding RNA makes up about 20%. Non-coding RNAs encompass a wide array of molecules, each …

May 3, 2025 · Non-coding RNAs (ncRNAs), which constitute a large majority of the human transcriptome, function as regulatory molecules that influence gene expression through specific …

Nov 15, 2023 · Abstract Non-coding RNAs (ncRNAs) are a heterogeneous group of transcripts that, by definition, are not translated into proteins.

Learn about the diverse classes of noncoding RNAs, the structures and origins of different ncRNA species, their biological functions, and clinical implications.
