Nanobiotechnology mainly deals with biological applications of materials and devices in which size range?
- A. 1-100 nanometres
- B. 1-100 millimetres
- C. 1-100 metres
- D. 1-100 kilometres
Answer: A. 1-100 nanometres
Nanobiotechnology involves materials at the nanoscale, generally 1-100 nm, where unique physical and chemical properties appear.

A researcher wants to compare a newly discovered DNA sequence with known sequences in databases. Which bioinformatics tool is most appropriate?
- A. BLAST
- B. Autoclave
- C. Centrifuge
- D. pH meter
Answer: A. BLAST
BLAST is used to find sequence similarity between a query DNA or protein sequence and sequences in databases.

Two bacterial genomes are compared, and several genes are found to be conserved in both. What is the most reasonable inference?
- A. These genes may perform important functions or indicate evolutionary relatedness
- B. Both bacteria must be the same species in all respects
- C. The genes cannot code for proteins
- D. The bacteria cannot have any mutations
Answer: A. These genes may perform important functions or indicate evolutionary relatedness
Conserved genes often perform essential functions and can also indicate common ancestry or evolutionary relationships.
Conserved genes often perform essential functions and can also indicate common ancestry or evolutionary relationships.
A researcher obtains the following results: gene X mRNA level is high, but the corresponding protein level is low. Which explanation is most appropriate?
- A. Post-transcriptional or translational regulation may be affecting protein production
- B. mRNA and protein levels must always be identical
- C. The genome has disappeared from the cell
- D. Proteomics cannot detect proteins in any condition
Answer: A. Post-transcriptional or translational regulation may be affecting protein production
Transcript levels do not always match protein levels because translation efficiency and protein stability can be regulated.
