Cis-acting asRNA is expressed as a complementary sequence of mRNA that becomes the sole target RNA. Therefore, cis-and trans-acting non-coding asRNAs are a major part of the asRNAs in …

Trans-regulatory element - Wikipedia

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 … WebCis-acting signals and trans-acting factors involved in influenza virus RNA synthesis Cis-acting signals and trans-acting factors involved in influenza virus RNA synthesis Authors R E O'Neill 1 , P Palese Affiliation 1 Department of Microbiology, Mount Sinai School of Medicine, New York, New York 10029.
