What is bioinformatics?

A. The study of living organisms only using microscopes
B. The use of computers to store, retrieve and analyze biological data ✓
C. The study of chemical reactions in plants only
D. The production of antibiotics by microorganisms

Answer: B. The use of computers to store, retrieve and analyze biological data
Bioinformatics involves applying computational tools to manage and analyze biological information such as DNA, RNA, and protein data.

Which database is most commonly used for protein sequence information?

A. GenBank
B. PDB
C. Swiss-Prot ✓
D. PubChem

Answer: C. Swiss-Prot
Swiss-Prot is a curated protein sequence database widely used for reliable protein information.

Protein informatics mainly deals with:

A. Only the synthesis of proteins in ribosomes
B. Collection, storage and analysis of protein-related data ✓
C. Only the chemical decomposition of proteins
D. Only the microscopic observation of tissues

Answer: B. Collection, storage and analysis of protein-related data
Protein informatics focuses on computational analysis of protein sequences, structures, and functions.

A researcher wants to find proteins with similar sequences to an unknown protein. Which tool is most suitable?

A. BLAST ✓
B. RasMol
C. PubChem
D. X-ray crystallography

Answer: A. BLAST
BLAST compares a query sequence against databases to find similar sequences.

A drug candidate shows strong binding to a target protein in computer simulation but fails in real experiments. Which is the most likely reason?

A. Computational models can predict interactions, but real biological systems are more complex ✓
B. Protein databases cannot store sequences correctly
C. All molecular models are always exact
D. Drug discovery does not use computers at all

Answer: A. Computational models can predict interactions, but real biological systems are more complex
Computer-based predictions are useful, but actual biological conditions, metabolism, and side effects may differ from simulations.
