How Cis-Regulatory DNA Controls Transcription

Cis-regulatory sequences are short, non-coding DNA segments that control gene transcription. They sit on the same chromosome as the genes they regulate and act as binding sites for transcriptional regulators. In eukaryotes, these proteins help control gene expression patterns in different cell types.

Transcriptional regulators are proteins that bind to short, specific stretches of non-coding DNA, known as cis-regulatory sequences. These essential components for gene regulation are present throughout the genome.
