Question

Which of the following is a data bank exclusively for proteins?

• A. DDBJ
• B. EMBL
• C. Genbank
• D. PDB

Hint:

• INSDC (GenBank, ENA/EMBL, DDBJ) Primary nucleotide sequence databases.
• UniProt (Swiss-Prot, TrEMBL) Primary protein sequence databases.
• PDB (Protein Data Bank) Database of 3D macromolecular structures (proteins and nucleic acids).
• Pay attention to "sequence" vs. "structure" and "nucleotide" vs. "protein".

Answer 1

The Correct Option is D

The correct choice for the data bank exclusively for proteins is PDB.

Here's a brief overview of each option:

• DDBJ: DNA Data Bank of Japan, primarily for nucleic acid sequences.
• EMBL: European Molecular Biology Laboratory, a database for nucleotide sequences.
• Genbank: A genetic sequence database for nucleotide sequences maintained by the NCBI.
• PDB: Protein Data Bank, a repository for the three-dimensional structural data of proteins and nucleic acids.

The Protein Data Bank (PDB) archives information about the 3D shapes of proteins and other complex biological molecules, making it the exclusive repository for protein structure data.
