What kind of database is NCBI?

The National Center for Biotechnology Information (NCBI) provides a large suite of online resources for biological information and data, including the GenBank® nucleic acid sequence database and the PubMed database of citations and abstracts for published life science journals.

By contrast, secondary databases comprise data derived from the results of analysing primary data. They are often referred to as curated databases but this is a bit of a misnomer because primary databases are also curated to ensure that the data in them is consistent and accurate.

Is NCBI a protein database?

NCBI's Protein resources include protein sequences and structures and related comparison and visualization tools, as well as databases and tools to predict and analyze functional domains.
