Why is chain of custody important in forensic biology, and what information is typically recorded?

• A. Records include date, time, and results but do not affect admissibility.
• B. Ensures evidence integrity and admissibility; records include date, time, handler identity, and transfer details.
• C. It is a minor administrative step with no impact on case outcomes.
• D. It only tracks storage temperature.

Answer: (B)

The key idea here is that chain of custody is about keeping a documented, unbroken record of who handled the evidence and when, from collection through analysis to presentation in court. This continuity shows the evidence hasn’t been altered, contaminated, or substituted and that proper procedures were followed at every step—critical for the evidence to be trusted and admissible in a forensic biology case. Typically, the records track who possessed the item and when, so you’d see the date and time of each transfer, the identity or signature of the person handling the evidence, and the transfer locations or containers. You’ll also find the case number, a description of the item, any seal or tamper-evident indicators, the condition of the item on transfer, and details about where the item was stored or moved to next. In short, it’s a running log that links every movement and handling step to preserve the integrity and admissibility of the evidence.
