Locus link was primarily developed to:
Locus link was primarily developed to:
Show Hint
NCBI has transitioned the features of LocusLink into the integrated NCBI Gene database, which acts as the primary hub for gene-specific information and nomenclature.
Updated On: Jun 19, 2026
- Provide three dimensional structures of proteins.
- Store taxonomic information of species.
- Provide information on official gene names.
- Provide information on metabolic pathways.
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept
Bioinformatics databases are structured repository archives designed to catalog genetic, genomic, taxonomic, or metabolic information.
Step 2: Defining LocusLink
LocusLink was developed by the National Center for Biotechnology Information (NCBI) to provide a single, centralized query interface to curated sequence and descriptive information for genetic loci. Its primary design focus was to provide stable, official gene names, symbols, and descriptions for genes across key model organisms, linking them directly to sequence data (Entrez, GenBank).
Step 3: Comparing Databases
- Protein 3D structures are cataloged in the Protein Data Bank (PDB).
- Taxonomic information is organized in the NCBI Taxonomy Database.
- Metabolic pathways are mapped in the Kyoto Encyclopedia of Genes and Genomes (KEGG).
Step 4: Conclusion
Hence, LocusLink was developed to provide official gene names and designations, matching option (C). Final Answer: (C)
