Cis und trans mutation

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 … WebNov 23, 2024 · Trans-regulatory divergence contributed more to the additively inherited genes than cis, however, its contribution to expression difference would be weakened as …

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. WebComplementation, cis, trans, dominant, and recessive are commonly used genetic terms. Their meaning can be clarified by considering a simple set of two genes that are transcribed from a single promoter, an operon. We shall consider the lac operon of Escherichia coli.
