Chromonomer

Definition

A chromonomer is a fundamental structural unit of a chromosome, consisting of a specific region of DNA that encodes genetic information and is organized in a functional manner. Chromonomers play a critical role in genome assembly evaluation and improvement, as they help researchers understand the organization of genes and regulatory elements within chromosomes, which is essential for accurate genome reconstruction and analysis.
