Question

based on the dna profile below, which suspect matches the crime scene dna?
chart with columns: crime scene dna, ladder, suspect 1, suspect 2, suspect 3, with bands
options:

• suspect 2
• suspect 3
• none of these
• suspect 1

Explanation:

Step1: Analyze DNA Band Patterns

Compare the band positions (lengths) of Crime Scene DNA with each Suspect. Each band in Crime Scene DNA must have a matching band in the Suspect's profile.

Step2: Check Suspect 1

Visually inspect bands: Crime Scene DNA bands match Suspect 1's bands in position and presence/absence.

Step3: Verify Other Suspects

Suspect 2 and 3 have bands not matching Crime Scene DNA (e.g., extra or missing bands).

Answer:

Suspect 1
