Learn to use WormBase, the primary resource for molecular and genetic information on Caenorhabditis elegans and related species. This resource contains not only genomic data but also has information on strains, phenotypes, cell and gene expression, and discussion forums on the C. elegans community. This all-inclusive resource is a critical tool for those using nematodes as a model organism for their research.

Note: The WormBase team has released a new interface, and we will update our materials to reflect this soon. The current material here refers to the legacy site, which remains accessible from http://legacy.wormbase.org/ at this time.

You will learn:

  • to perform Quick Searches and navigate gene summary pages
  • to browse genetic features within the context of the entire chromosome
  • to construct complex queries across various sets of data stored within WormBase
  • to perform nucleotide or amino acid sequence homology searches
