What is bioinformatics?

A. The study of fossils and ancient life forms
B. The use of computers to store, retrieve, and analyse biological data ✓
C. The study of plant and animal tissues under a microscope
D. The process of breeding organisms for desired traits

Answer: B. The use of computers to store, retrieve, and analyse biological data
Bioinformatics combines biology and computational tools to manage and analyse biological information such as sequences and genomes.

Which of the following is a primary biological database?

A. GenBank ✓
B. PubMed
C. PDBsum
D. OMIM

Answer: A. GenBank
GenBank is a primary database because it stores original nucleotide sequence data submitted by researchers.

A student wants to find known information about a gene, including its function and related disease links. Which database is most appropriate?

A. Primary sequence database
B. Secondary database ✓
C. Literature-only database
D. Protein expression lab notebook

Answer: B. Secondary database
