promiscuous

pruh-MIS-kyoo-uhs

Definition

Characterized by indiscriminate or random interactions rather than specific, regulated ones.

Etymology

Derived from the Latin 'promiscuus', meaning 'mixed' or 'indiscriminate', formed by the prefix 'pro-' meaning 'forward' and the root 'miscere' meaning 'to mix'.

In the news

In this context, the word describes how the protein GCN4 binds non-specifically or inappropriately to DNA sites it is not intended to regulate. Suppressing this behavior is essential for ensuring precise genetic control.
