WebOct 10, 2015 · Gene promoters and enhancers are examples of cis -regulatory regions (Table 1) that often show nucleosome depletion. At the promoters of highly expressed genes, nucleosomes are located just upstream and downstream of the transcription start site (TSS), thereby creating a nucleosome depleted region. WebApr 15, 2024 · Differential gene expression mechanisms ensure cellular differentiation and plasticity to shape ontogenetic and phylogenetic diversity of cell types.

"An example of a cis-acting regulatory sequence is the operator in the lac operon. This DNA sequence is bound by the lac repressor, which, in turn, prevents transcription of the adjacent genes on the same DNA molecule. The lac operator is, thus, considered to "act in cis" on the regulation of the nearby … See more Cis-regulatory elements (CREs) or Cis-regulatory modules (CRMs) are regions of non-coding DNA which regulate the transcription of neighboring genes. CREs are vital components of genetic regulatory networks, … See more Cis-regulatory modules can be characterized by the information processing that they encode and the organization of their transcription factor binding sites. … See more The function of a gene regulatory network depends on the architecture of the nodes, whose function is dependent on the multiple cis-regulatory modules. The layout of cis-regulatory modules can provide enough information to generate spatial and … See more Besides experimentally determining CRMs, there are various bioinformatics algorithms for predicting them. Most algorithms try to … See more The genome of an organism contains anywhere from a few hundred to thousands of different genes, all encoding a singular product … See more CREs have an important evolutionary role.
