Choose the cis-elements.

Click on the cis regulatory elements only.

Control of eukaryotic gene expression (gene control) can occur at multiple levels from DNA accessibility to post-translational changes to polypeptides/proteins.

Silencers, repressors, transcription factors, activators, enhancers, insulators, histone acetyltransferases (HATs), histone deacetylases (HDACs), histone remodellers and DNA methyltransferases all play a role in gene control.

Answer #1

Cis-regulatory elements are the DNA sequences which are non-coding and regulate the expression of neighbouring (genes in the vicnity) genes. These sequences are bound by transcription factors for regulation of transcription.

Out of the given options, the examples of Cis-elements are Silencers, Enhancers, Insulators

Others options are transacting as they distantly control the gene expression either by binding to the cis-regulatory elements or by bringing modifications in DNA to make it accessible for other transacting elements.
