WebApr 20, 2024 · If this locus is within some kind of threshold distance of the gene encoding protein X, perhaps 2Mb, then it is known as a 'cis' ('on the same side as'). Otherwise, if the locus is found distal to gene encoding protein X, it is known as a 'trans' locus. Similarly, ' cis' regulatory elements are regions of non-coding DNA which regulate the ... Trans-acting factors can be categorized by their interactions with the regulated genes, cis-acting elements of the genes, or the gene products. DNA binding trans-acting factors regulate gene expression by interfering with the gene itself or cis-acting elements of the gene, which lead to changes in transcription activities. This can be direct initiation of transcription, promotion, … binely news quiz
