The easiness of maintaining and propagating the nematode C. elegans make it a nice model organism to work with. The possibility of synchronizing worms allows the work with a significant amount of subjects at the same developmental stage, what facilitates the study of one particular process in many animals.

Screening for mutants with phenotypic defects is a straightforward method for identifying genes that function in a given biological process. In this article we describe how to culture free living worms (e.g., Pristionchus pacificus) in the laboratory and show two different mutagenesis methods, EMS and TMP/UV.
FAQs
Their transparent bodies allow researchers to observe cellular processes directly as they occur. This feature is especially useful for tracking cell division, programmed cell death, and developmental changes without focusing only on final outcomes. By following these events in the living animal, investigators can connect changes in genes or environmental conditions with visible biological responses.
Researchers alter genes or environmental conditions and then monitor changes in traits such as movement, behavior, development, aging, or reproduction. Comparing these responses helps link a specific biological change with its consequences in the organism. This approach supports investigations of gene function because molecular changes can be evaluated alongside observable cellular or whole-animal outcomes.
Conserved molecular pathways connect processes in C. elegans with fundamental mechanisms found across animals. When a pathway influences development, nervous-system biology, aging, or disease-related processes in the worm, it can provide principles for studying more complex organisms. The model therefore serves as a tractable system for examining biology that extends beyond the species itself.
A typical investigation begins by manipulating a gene or environmental condition, followed by observation of the resulting biological response. Researchers can track cellular processes as well as movement, behavior, aging, or reproduction across the animal's short life cycle. The outcome is then used to evaluate how the tested factor affects development or other biological functions.
Researchers can examine cell division and programmed cell death to study cellular and developmental mechanisms. They can also track movement, behavior, aging, and reproduction to evaluate effects at the whole-animal level. Using several of these outcomes together helps connect cellular changes with nervous-system function, development, life-history traits, or broader disease-related mechanisms.
C. elegans supports research across gene function, nervous-system biology, development, aging, and reproduction because its development and cellular processes can be observed while genes or environmental conditions are manipulated. Its conserved molecular pathways make findings relevant to broader animal biology. Studies in this model can therefore help identify fundamental mechanisms that guide research in more complex organisms.
