An internal control region (ICR) is a segment of DNA that regulates the expression of nearby genes. It plays a crucial role in gene transcription, ensuring that genes are expressed at the right levels and at the right times within a cell. Internal control regions can contain various elements, such as enhancers, silencers, and promoter regions, which interact with transcription factors and other regulatory proteins to modulate gene expression.
