Which statement about the function of bioinformatics in DNA biotechnology is most accurate?

• A. It replaces laboratory experiments with purely computational results.
• B. It analyzes sequence data, designs primers, interprets genomic information, and helps predict protein structure.
• C. It only stores DNA sequences without analysis.
• D. It cures diseases by itself.

Answer: (B)

Bioinformatics in DNA biotechnology is about turning genetic data into actionable insights that guide experiments. The statement that best matches this role says it analyzes sequence data to understand what the DNA encodes, designs primers for amplification and testing, interprets genomic information to annotate genes and variants, and helps predict protein structure to infer function. This captures how computational tools help dissect sequences, plan experiments, interpret what genetic changes mean, and anticipate how a protein might behave, guiding further work in the lab. It’s not about replacing lab experiments with purely computational results, nor about merely storing sequences without analysis, and it certainly doesn’t cure diseases by itself—the real power lies in integrating in silico analysis with experimental validation to advance understanding and development.
