Mock test Set-5

Q1. Which of the following is NOT a method used in forensic anthropology for estimating the stature of an individual from skeletal remains?

   a) Fully's method 

   b) Trotter and Gleser's method 

   c) Gustafson's method 

   d) Pearson's formula 

Answer: c) Gustafson's method 

Explanation: Gustafson's method is used for age estimation based on dental wear, not for estimating stature. Fully's method, Trotter and Gleser's method, and Pearson's formula are all used for estimating stature from skeletal remains.

 

Q2. In the context of forensic document examination, "ESDA" stands for:

   a) Electrostatic Detection Apparatus 

   b) Electromagnetic Spectrum Detection Analysis 

   c) Electronic Signature Detection Algorithm 

   d) Enhanced Spectral Document Analysis 

Answer: a) Electrostatic Detection Apparatus 

Explanation: ESDA is used to detect indented writing on documents, which is crucial for uncovering hidden information and verifying document authenticity.

 

Q3. Which type of firearm leaves striation marks on the bullet that can be used for forensic comparison?

   a) Smoothbore shotgun 

   b) Rifled handgun 

   c) Air rifle 

   d) Muzzleloader 

Answer: b) Rifled handgun 

Explanation: Rifled firearms have grooves inside the barrel that impart striation marks on bullets, which can be matched to a specific weapon.

 

Q4. In forensic toxicology, the term "zero-order kinetics" refers to:

   a) A constant rate of drug metabolism regardless of concentration 

   b) A variable rate of drug metabolism proportional to concentration 

   c) The initial phase of drug absorption 

   d) The time it takes for half of the drug to be metabolized 

Answer: a) A constant rate of drug metabolism regardless of concentration 

Explanation: Zero-order kinetics implies that the drug is metabolized at a constant rate, independent of its concentration in the body, often observed with high doses of certain substances like alcohol.

 

Q5. Which of the following analytical techniques is used to determine the elemental composition of a sample in forensic science?

   a) GC-MS (Gas Chromatography-Mass Spectrometry) 

   b) FTIR (Fourier Transform Infrared Spectroscopy) 

   c) AAS (Atomic Absorption Spectroscopy) 

   d) NMR (Nuclear Magnetic Resonance) 

Answer: c) AAS (Atomic Absorption Spectroscopy) 

Explanation: AAS is used to analyze the elemental composition of samples by measuring the absorption of light by free atoms.

 

Q6. The "Balthazard formula" is used in forensic science to:

   a) Estimate the postmortem interval 

   b) Determine the probability of a match between fingerprint patterns 

   c) Calculate the angle of blood spatter impact 

   d) Estimate the probability of random match in DNA profiling 

Answer: b) Determine the probability of a match between fingerprint patterns 

Explanation: The Balthazard formula is used to calculate the probability of two fingerprint patterns matching by chance, considering the minutiae points.

 

Q7. Which forensic technique is used for the detection of explosive residues?

   a) Raman spectroscopy 

   b) Ion Mobility Spectrometry (IMS) 

   c) Thin Layer Chromatography (TLC) 

   d) Capillary Electrophoresis 

Answer: b) Ion Mobility Spectrometry (IMS) 

Explanation: IMS is widely used for detecting explosive residues due to its sensitivity and ability to separate ions based on their mobility in a gas phase.

 

Q8. The technique known as "touch DNA" is primarily used to:

   a) Identify DNA from bodily fluids 

   b) Recover DNA from skin cells left on objects 

   c) Amplify degraded DNA samples 

   d) Compare mitochondrial DNA sequences 

Answer: b) Recover DNA from skin cells left on objects 

Explanation: Touch DNA refers to the collection and analysis of DNA left behind from skin cells when an individual touches an object.

 

Q9. In forensic odontology, the "cementoenamel junction" is an important landmark for:

   a) Estimating age based on tooth wear 

   b) Determining the type of tooth 

   c) Assessing dental trauma 

   d) Comparing bite marks 

Answer: a) Estimating age based on tooth wear 

Explanation: The cementoenamel junction (CEJ) is the boundary where the enamel covering the tooth crown meets the cementum covering the root, useful in age estimation by examining wear and changes.

 

Q10. Which forensic technique uses isotopic analysis to determine geographic origin or travel history of an individual?

   a) DNA sequencing 

   b) Hair analysis 

   c) Stable isotope analysis 

   d) Trace element analysis 

Answer: c) Stable isotope analysis 

Explanation: Stable isotope analysis examines the ratios of isotopes in biological materials, providing information about an individual's geographic origin or movements based on the isotopic composition of consumed water and food.
