+**Restriction** broadly refers to the act of limiting or controlling an action or resource. In [Molecular Biology](/wiki/molecular_biology), a [restriction enzyme](/wiki/restriction_enzyme) precisely cuts DNA at specific recognition sites, a fundamental process for genetic manipulation. This concept underscores how boundaries can define structure and enable function across various domains.
