N2

N2

The Laboratory Nematode breed N2, often referred to simply as N2, is a widely used strain of the nematode species *Caenorhabditis elegans*. N2 is the standard wild-type stock and serves as the foundational reference strain for a wide array of biological research due to its well-studied genetic background. Originating from a collection made in Bristol, England in the mid-20th century, the N2 strain has been fundamental in studies exploring genetics, neurobiology, and developmental biology, making it an indispensable model organism in laboratory environments worldwide.

Characterized by its transparency, rapid life cycle, and manageable size, the N2 strain provides a comprehensive model for understanding complex biological processes. On a molecular level, its genome is fully sequenced, allowing for precise genetic manipulation and the study of mutations, which facilitates groundbreaking research in fields such as aging, disease, and behavior. In terms of behavior and morphology, N2 exhibits typical *C. elegans* features, including a simple nervous system and distinctive wriggling movement. This strain lays the groundwork for comparison with mutant strains, enhancing our understanding of gene function and biological pathways across many species, including humans.
