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 … WebFinal answer. Which of the following statements about cis- and trans-acting regulatory elements is FALSE? A loss-of-function mutation of a cis-acting operator can be dominant to wild type, in a diploid genotype. If a cis-acting regulatory element is deleted form an operon and reinserted by itself on a different chromosome, the expression of 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, … WebJul 29, 2009 · Cis-acting regulatory sequences are required for the proper temporal and spatial control of gene expression. Variation in gene expression is highly heritable and a significant determinant of human disease susceptibility.

WebJul 23, 2024 · Cis-regulatory mutations in diploid organisms can be defined as those that change gene expression in an allele-specific manner; while trans-regulatory mutations influence gene expression in a diffusible manner, such as mutations in transcription factors (Emerson and Li 2010).
