Unraveling Clues: Forensic Techniques in Action

The video tutorial explores forensic investigation techniques, focusing on fingerprint analysis, DNA extraction, and odorology. It demonstrates how fingerprints are unique and can be revealed using powder or fuming techniques. DNA analysis is explained as a method to identify individuals when fingerprints are unavailable. Odorology, using trained dogs to identify human odors, is introduced as a supplementary technique. The video highlights the advancements in forensic science that aid in identifying culprits efficiently.

What makes fingerprints a reliable method for identifying individuals?

• They can be easily altered.

• They are the same for everyone.

• They change over time.

• They are unique to each person.

Which method is commonly used to reveal fingerprints at a crime scene?

• Fingerprint powder

• Magnetic fields

• Water spray

• Heat application

What is the advantage of the new fingerprint fuming technique?

• It is more expensive.

• It takes longer to process.

• It provides high-quality prints quickly.

• It requires more equipment.

What is DNA and why is it important in forensic science?

• A chemical used in labs

• A unique genetic code

• A type of crime scene evidence

• A type of fingerprint

How is DNA collected from a crime scene?

• By taking a photo

• With a magnet

• With a cotton swab

• Using a brush

What is odorology?

• The use of visual evidence

• The identification of human odors

• The analysis of DNA

• The study of fingerprints

Why are dogs used in odorology?

• They have a superior sense of smell.

• They can run faster.

• They have a better sense of sight.

• They are easier to train than humans.
