What is the term used to describe a piece of evidence that is indirectly related to the crime but can still help in solving the mystery?

  1. Direct evidence

  2. Circumstantial evidence

  3. Testimonial evidence

  4. Forensic evidence
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Circumstantial evidence is a piece of evidence that is indirectly related to the crime but can still help in solving the mystery.

Multiple choice

  1. A test to determine the most effective drug for a particular patient based on their genetic makeup.

  2. A test to identify genetic variations that may increase the risk of developing a disease.

  3. A test to monitor drug levels in a patient's blood.

  4. A test to diagnose a disease based on genetic markers.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Pharmacogenomic tests are used to determine the most effective drug for a particular patient based on their genetic makeup, helping to optimize drug selection and reduce adverse reactions.

Multiple choice

Which technique is used to separate DNA fragments based on their size?

  1. Polymerase Chain Reaction (PCR)

  2. Southern Blotting

  3. DNA Sequencing

  4. Gel Electrophoresis
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Gel Electrophoresis is a technique used to separate DNA fragments based on their size by applying an electric field to a gel containing the DNA samples.

Multiple choice

Which technique is used to detect specific DNA sequences in a sample?

  1. Polymerase Chain Reaction (PCR)

  2. Southern Blotting

  3. DNA Sequencing

  4. Restriction Fragment Length Polymorphism (RFLP)
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Southern Blotting is a technique used to detect specific DNA sequences in a sample by transferring DNA fragments from a gel onto a nitrocellulose membrane and hybridizing them with a labeled DNA probe.

Multiple choice

Which technique is used to identify variations in DNA sequences among individuals?

  1. Polymerase Chain Reaction (PCR)

  2. Southern Blotting

  3. DNA Sequencing

  4. Restriction Fragment Length Polymorphism (RFLP)
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Restriction Fragment Length Polymorphism (RFLP) is a technique used to identify variations in DNA sequences among individuals by analyzing the lengths of DNA fragments generated by restriction enzyme digestion.

  1. PCR

  2. DNA Sequencing

  3. Southern Blotting

  4. Northern Blotting
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

PCR (Polymerase Chain Reaction) is a technique used to amplify a specific DNA sequence, allowing for the detection and analysis of even small amounts of DNA.

Multiple choice

What is the primary role of a forensic anthropologist?

  1. To identify human remains

  2. To determine the cause of death

  3. To reconstruct the crime scene

  4. To collect evidence for law enforcement
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The primary role of a forensic anthropologist is to identify human remains, often in cases where the remains are badly decomposed or fragmented.

Multiple choice

Which of the following is NOT a method used by forensic anthropologists to identify human remains?

  1. DNA analysis

  2. Dental records

  3. Fingerprint analysis

  4. Anthropometric measurements
