  1. Burrard
  2. Nickolls
  3. Henry
  4. Rudolph Ross

Answer: (1) Burrard

2. G.E.Q.D. is not at the following place:

  1. Kolkata
  2. Hyderabad
  3. Delhi
  4. Shimla

Answer: (3) Delhi

In India (till 2022), there are only three GEQD (Government Examiner Of Questioned Documents) departments which are situated in Kolkata, Hyderabad, and Shimla. However, in 2014, the Ministry of Home Affairs (MHA) decided to merge three GEQDs with their respective CFSLs, (Shimla with CFSLs in Chandigarh).
-> 1st GEQD: Shimla (1906) (also the second oldest GQEDin the world after Scotland Yard)
-> 2nd GEQD: Kolkata (1963)
-> 3rd GEQD: Hyderabad (1968)

3. The science of fingerprint was demonstrated by

  1. Syndey Smith
  2. Francis Galton
  3. Spilsbury
  4. Issac Newton

Answer: (2) Francis Galton

-> The science of fingerprints was demonstrated by Francis Galton.
-> The book named “Finger Prints” was published by Galton.
-> In 1892, he categorized fingerprints into three classes i.e. Arches, Whorls, and Loops.

4. Exciter Filter is used in

  1. Polarising Microscope
  2. Scanning Electron Microscope
  3. Stereoscopic microscopic
  4. Fluorescent Microscope

Answer: (4) Fluorescent Microscope

-> In a fluorescent microscope, an excitation filter is used to provide high-quality optical-glass filtering and selection measures for the required excitation wavelength of light.
-> In short, it is a high-quality wavelength selection filter.

5. The following gas is used as carrier gas in GLC:

  1. Hydrogen
  2. Argon
  3. Nitrogen
  4. Helium

Answer: (4) Helium

-> Helium gas acts as a carrier for the GLC operations.
-> It provides good efficiency and analysis but with a high costing price. Another GLC gas is nitrogen (best efficiency but extremely slow) hence their application is very less.

6. Bloodstained clothes collected from the scene of the crime should be sent for examination

  1. As such without drying
  2. After drying in sun
  3. After drying in shade
  4. After drying in shade at room temperature

Answer: (4) After drying in shade at room temperature

If the sample is sent without drying then there is a higher chance of getting infected by bacterial and fungal growth. Moreover, enzyme activity also increases the degradation of the blood constitution.
-> Therefore, the clothes must be dried first at room temperature (not in sunlight).

7. Leucomalochite Green test is done for the examination of the following

  1. Urine
  2. Sweat
  3. Saliva
  4. Blood

Answer: (4) Blood

-> Leucomalochite Green is a presumptive test for blood that is based on the action of peroxidase activity by Hb.
-> Hb molecules react and cleave the oxygen molecules from H2O2 (hydrogen peroxide) which catalyzes the reduced form of leucomalochite green to the oxidized form of blue-green color product.

8. The full name of N.M.R. is

  1. Nuclear Magnetic Resolution
  2. Nuclear Magnetic Remittance
  3. Nuclear Magnetic Resonance

  2. Thymine
  3. Guanine
  4. None of the above

Answer: (2) Thymine

In nucleotides base-pair combination, Adenine is always paired with thymine. While Guanine is always paired with Cytosine. Remember: AT Goal Course

10. Soft X-rays are useful for the examination of

(i) Paintings (ii) Jewellery (iii) Hidden Objects (iv) Loaded Dices

  1. (i) and (iii)
  2. (ii) and (iii)
  3. (iii) and (iv)
  4. (i) and (ii)

Answer: (4) Both Paintings and Jewellery

-> Art laboratories use a series of “soft” x-rays which are also known as the Grenz rays which have a longer wavelength and are less intensive which makes them an ideal tool for art authentications.
-> Hard x-rays are the highest energy x-rays whose energies are greater than 10keV. They are used to detect metal objects and other non-biological things.

11. Heptoglobine occurs in blood

  1. R.B.C.
  2. W.B.C.
  3. Serum
  4. All of these

Answer: (4) All of these

Haptoglobin is a protein that is present in RBC, blood serum, and WBC. This protein is produced by the liver and its function is to clear free Hb from the circulation.

12. KBr Pellet is to be used in the following examination

  1. UV spectrometry
  2. Visible Spectrometry
  3. IR spectrometry
  4. Atomic Absorption Spectrometry

Answer: (3) IR spectrometry

In IR spectrometry forensic analysis, window materials should be transparent within the mid-IR region (5000 – 400 cm-1), and those can be achieved only by using KBr pellets, as they have a larger transmission window in the IR. And that is the reason why Potassium bromide (KBr) typically uses a window material in the IR. Inshort, KBr remains transparent in IR.

  3. Insecticides
  4. Non-volatile Organic poisons

Answer: (4) Non-volatile Organic poisons

For extraction of non-volatile organic poison, common extraction methods are solvent extraction, Stas-Otto, Digestion with ammonium sulphate. Some modern methods of non-volatile organic poisons are paired ion extraction chromatography, HPTLC, and solid-phase extraction.

In solvent extraction, the 50gm of viscera are mixed with 5 gm of ammonium sulphate and 100 ml of diethyl ether. The mixture is then mixed and kept overnight.

24. Assertion(A): In the case of a bullet injury entry wound is smaller than the exit wound.
Reason(R): Bullet is distorted inside the body.

  1. Both (A) And (R) are true
  2. Both (A) and (R) are false
  3. (A) is true but (R) is false
  4. (A) is false but (R) is true

Answer: (1) Both (A) And (R) are true

In the bullets’ exit wound, the bullet takes the body’s internal parts such as tissues in their outward motion (and sometimes also gets distorted) which results in the exit wound with a larger diameter.
