✍️ Sample BACE Questions & Answers

1. A biotechnician needs to confirm media has cooled enough after autoclaving before adding heat-sensitive supplements. Which tool is most appropriate?

✓ A calibrated digital thermocouple or infrared thermometer

A calibrated digital thermocouple or infrared thermometer provides accurate, non-contact or low-contact temperature measurement suitable for monitoring media cooling safely.

2. What does 'GDP' (Good Documentation Practices) require when correcting an error in a paper record?

✓ Draw a single line through the error, write the correction alongside, add initials, date, and reason for correction

GDP requires a single strikethrough that keeps the original entry readable, with the correction, signature/initials, date, and reason noted — never erasing or obscuring original entries.

3. Which macromolecule serves as the primary source of energy for most organisms?

✓ Carbohydrates

Carbohydrates are the primary and most readily available source of energy for most organisms. They are broken down through cellular respiration to produce ATP, the main energy currency of the cell. Glucose, a simple carbohydrate, is a key molecule in this energy-generating pathway.

4. What is the primary purpose of a 'Site Master File' (SMF) in pharmaceutical cGMP?

✓ It is a comprehensive document describing a facility's GMP operations submitted to regulatory authorities to facilitate drug product approval

A Site Master File provides regulatory authorities with a comprehensive description of a manufacturing facility's GMP systems, processes, and controls to support regulatory review.

5. What is a 'wet mount' preparation in light microscopy?

✓ A specimen suspended in a drop of liquid between a slide and coverslip

A wet mount places a specimen in a drop of water or buffer covered by a coverslip, allowing observation of live or unstained specimens.

6. Why must you never use a mercury thermometer in a laboratory incubator or water bath?

✓ If broken, mercury vapor and liquid mercury create serious health and environmental hazards that are difficult to remediate

Mercury is a potent neurotoxin; breakage releases mercury vapor and liquid mercury requiring specialized, costly cleanup and posing serious health risks to laboratory staff.
