Question

Which database provides non-redundant protein sequences?

• A. GenBank
• B. UniProt
• C. PDB
• D. KEGG

Hint:

Remember: \[ \boxed{ \begin{aligned} \text{UniProt} &\rightarrow \text{Protein sequences} \text{PDB} &\rightarrow \text{Protein structures} \text{KEGG} &\rightarrow \text{Biological pathways} \end{aligned} } \]

Answer 1

The Correct Option is B

Step 1: Recall the purpose of UniProt. UniProt is a comprehensive protein database that provides curated, non-redundant protein sequence and functional information.

Step 2: Eliminate the other options.
• GenBank stores nucleotide sequences.
• PDB stores three-dimensional structures.
• KEGG provides metabolic and signaling pathways. Thus, \[ \boxed{\text{UniProt}} \] is the correct answer. Therefore, \[ \boxed{(B)} \] is the correct answer.
