Chapter 9: Introduction to Bioinformatics — Important Questions & Answers
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.
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
Secondary databases provide analysed and curated information, such as functional details and disease associations.

Why is sequence alignment important in genome analysis?
- A. It helps determine the similarity and evolutionary relationship between sequences
- B. It increases the length of DNA molecules
- C. It changes the base composition of DNA
- D. It prevents mutations in chromosomes
Answer: A. It helps determine the similarity and evolutionary relationship between sequences
Alignment helps identify conserved regions and infer functional or evolutionary relationships among sequences.
Alignment helps identify conserved regions and infer functional or evolutionary relationships among sequences.
Which statement about biological databases is CORRECT?
- A. Primary databases contain data that are derived only after analysis
- B. Secondary databases store raw sequence data directly submitted by researchers
- C. GenBank is a primary database that stores nucleotide sequences
- D. Bioinformatics does not use databases
Answer: C. GenBank is a primary database that stores nucleotide sequences
GenBank is a well-known primary database that stores raw nucleotide sequence data submitted by scientists.
