Summary
Non-protein coding RNAs, alongside DNA and proteins, create a regulatory hierarchy. This system controls chromatin folding and gene expression, enabling cell-specific transcription.
Area of Science:
- Molecular Biology
- Genetics
- Epigenetics
Background:
- Recent sequencing technologies reveal numerous non-protein coding RNAs (ncRNAs).
- ncRNAs are crucial regulators of gene expression, acting alongside proteins and epigenetic modifications.
- These elements contribute to the complex control of transcription.
Purpose of the Study:
- To propose a structural and functional hierarchy for gene regulation.
- To elucidate the roles of DNA, proteins, and ncRNAs in chromatin folding and transcriptional control.
Main Methods:
- This is a perspective piece, synthesizing existing knowledge.
- It focuses on conceptualizing a hierarchical model of gene regulation.
Main Results:
- A hierarchical model is proposed where DNA, proteins, and ncRNAs interact.
- These interactions modulate chromatin's three-dimensional structure.
- This modulation establishes context for cell-specific transcription.
Conclusions:
- ncRNAs are integral components of a regulatory hierarchy controlling gene expression.
- The interplay between DNA, proteins, and ncRNAs dictates chromatin organization and cell-specific transcription.

Structure of a Gene
A gene is the fundamental unit of heredity. Every individual has two copies of each gene, one inherited from each parent. Although most people contain the same genes, there is a small fraction that is slightly different amongst people. A gene with a small difference in its sequence of DNA bases forms different alleles, contributing to different phenotypes.
However, only 1% of the DNA is composed of genes that encode proteins; the rest, 99% is non-coding DNA. This non-coding DNA performs...

Regulation of Expression Occurs at Multiple Steps
Gene expression can be regulated at almost every step from gene to protein. Transcription is the step that is most commonly regulated. This involves the binding of proteins to short regulatory sequences on the DNA. This association can either promote or inhibit the transcription of a gene associated with the respective sequence.
Transcription results in the generation of precursor (pre-mRNA) that consists of both exons and introns, which needs further processing before being translated to a...

What is Gene Expression?
Overview
Gene expression is the process in which DNA directs the synthesis of functional products, that is, proteins. Cells can regulate gene expression at various stages. It allows organisms to generate different cell types and enables cells to adapt to internal and external factors.
Genetic Information Flows from DNA to RNA to Protein
A gene is a stretch of DNA that serves as the blueprint for functional RNAs and proteins. Since DNA is made up of nucleotides and proteins consist of amino...

What is Gene Expression?
A gene is a stretch of DNA that serves as the blueprint for functional RNAs and proteins. Since DNA is comprised of nucleotides and proteins are comprised of amino acids, a mediator is required to convert the information encoded in DNA into proteins. This mediator is the messenger RNA (mRNA). mRNA copies the blueprint from DNA by a process called transcription. In eukaryotes, transcription occurs in the nucleus by complementary base-pairing with the DNA template. The mRNA is then processed and...
