your answer

colin pitchfork
alec jeffreys
albert einstein
edmond locard

Explanation:

First Question (Multiple Choice)

To determine the database housing DNA profiles:

• FBI is a law - enforcement agency, not a DNA - profile database.
• CODIS (Combined DNA Index System) is the database that stores DNA profiles for forensic use.
• AFIS is an Automated Fingerprint Identification System, not for DNA.
• LANTUS is a diabetes medication, unrelated to DNA.

A limitation of DNA as forensic evidence: Contamination is a major issue. If DNA samples are contaminated during collection, handling, or analysis, it can lead to inaccurate results. For example, if a technician accidentally transfers their own DNA or DNA from another sample to the evidence sample, the resulting profile may be incorrect and mislead the investigation. Also, DNA evidence can be misinterpreted in cases of partial or mixed profiles, especially when dealing with samples from multiple individuals.

To identify the scientist behind DNA - profile identification in criminal cases:

• Colin Pitchfork was a criminal caught using DNA profiling, not the creator.
• Alec Jeffreys developed DNA profiling for use in criminal identification.
• Albert Einstein was a physicist, not related to DNA profiling.
• Edmond Locard is known for the Locard's Exchange Principle in forensics, not DNA profiling.

Answer:

B. CODIS
