Mapping regulatory elements is important for several reasons: 1. Gene Expression Control: By identifying these elements, researchers can understand how gene expression is regulated in different cell types and tissues. 2. Disease Mechanisms: Abnormalities in regulatory elements can lead to diseases such as cancer. Mapping these elements can help identify potential therapeutic targets. 3. Developmental Biology: Regulatory elements play a crucial role in embryonic development and differentiation. Understanding these elements can shed light on developmental processes and congenital diseases.
