WebMay 20, 2024 · The cis-acting RNA elements are specific sequences the viral replicase and related host factors can recognize to initiate the replication complex [65, 66]. Therefore, although viral RNA is only a small fraction of the total RNA in a cell, the viral RNA has a significant advantage to ensure that viral RNA, instead of host RNA, was replicated. WebTherefore the transcription initiation complex is composed of promoter sequences and DNA binding proteins. These two components of transcription are normally described as cis …
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 … See more Cis-regulatory elements (CREs) or Cis-regulatory modules (CRMs) are regions of non-coding DNA which regulate the transcription of neighboring genes.
