WebBased on our actual understanding of epigenetics, an epigenetic trait is broadly intended as a reversible molecular modification associated with changes in gene expression in the absence of variation in genomic DNA sequence, occurring in the course of adaptive responses of a given cell/organism to environmental influence [ 79, 80 ]. WebJun 14, 2024 · Prokaryotic Gene Regulation. In bacteria and archaea, structural proteins with related functions are usually encoded together within the genome in a block called an operon and are transcribed together under the control of a single promoter, resulting in the formation of a polycistronic transcript (Figure \(\PageIndex{1}\)).
WebThese mechanisms include (i) regulation of transcription by DNA methylation, histone modifications, and transcription factors, (ii) RNA splicing, (iii) RNA-mediated post-transcriptional silencing, (iv) organellar translation, (v) protein processing by truncation, (vi) post-translational chemical modifications, (vii) protein folding, and (viii ... WebThe regulation of gene expression begins before transcription, the first stage of protein synthesis. Regulatory proteins called transcription factors dictate which genes are expressed (turned 'on') and which genes are not expressed (turned 'off'). The diagram below illustrates the binding of a transcription factor to DNA.
