WebA loss-of-function mutation of a cis-acting operator can be dominant to wild type, in a diploid genotype. Cis-acting elements may be sites for either positive or negative regulation If a trans-acting regulator is transposed to a different chromosome, the expression of the genes that it regulates will not change.

WebDec 12, 2024 · For mutations that impact gene expression, mutations acting in cis have been hypothesized to generally be less pleiotropic than mutations affecting the same … 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 genes. The operator itself does not code for any protein or RNA. In contrast, trans-regulatory elements are diffusible factors, usually proteins, that may modify the …
