Abstract:
Cell phenotype does not only depend on the nucleotide sequence, but is determined by those genes that are expressed and those that are not. One way to regulate this gene expression pattern is by modifying the chromatin structure via diverse epigenetic mechanisms. In the present article we present the most important epigenetic mechanisms: deoxyribonucleic acid methylation, histone post-translational modifications, non-coding ribonucleic acid mediated gene-silencing, ATP-dependent chromatin remodeling, and Polycomb and Trithorax group proteins.

What is Gene Expression?
What is Gene Expression?
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...
Regulation of Expression Occurs at Multiple Steps
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...
