Genetic regulatory proteins regulate what aspect of gene expression?

Genetic regulatory proteins regulate gene expression by controlling whether a gene is transcribed and how much RNA is produced. They bind to DNA at promoter or control regions and influence the recruitment and activity of RNA polymerase, acting as activators or repressors. In bacteria, repressors block transcription while activators enhance it; in eukaryotes, transcription factors and chromatin modifiers adjust accessibility and transcription levels. This role is distinct from catalysis (enzymes speeding up chemical reactions), providing structural components, or transporting molecules.
