  1. Direct bombardment with electrons
  2. Bombardment with protons
  3. Irradiation with X-rays of shorter wavelengths
  4. All the above

Answer and Explanation

Answer: (4) All the above

No explanation is required for this question of 2013 December Forensic Science Paper 3 of UGC NET NTA/JRF.

10. Bertrand lens is a part of the following microscope:

  1. Steriomicroscope
  2. Comparison microscope
  3. Polarising microscope
  4. Fluorescence microscope

Answer and Explanation

Answer: (3) Polarising microscope

Bertrand Lens are commonly employed in the polarizing microscope. These lenses are the type of small convergent lens that is located between the objective and eyepieces of the polarized microscope. It allows users to see conoscopic interference patterns (pattern of birefringent colors crossed by dark bands) of the sample. These patterns are useful for the identification and investigation of the optical properties of minerals.

11. In which of the method, Hollow-Cathode lamp is used as radiation source?

  1. Atomic absorption spectrophotometer
  2. UV-Vis spectrophotometer
  3. IR spectrophotometer
  4. Raman spectrophotometer

Answer and Explanation

Answer: (1) Atomic absorption spectrophotometer

Hollow cathode lamps (HCL) are discharge lamps that consist of a cathode, an anode, and an inert gas-filled in a glass envelope which is designed for the use in Atomic Absorption Spectrometer (AAS).

12. A lens with a variable focal length is known as:

  1. Normal lens
  2. Telephoto lens
  3. Wide-angle lens
  4. Zoom lens

Answer and Explanation

Answer: (4) Zoom lens

-> Telephoto lens: long-focal length that is great for bringing distant scenes and subjects closer. It can either have prime (fixed focal length) and zoom focal lenses.
-> Wide-angle lens: wider angle of view of 64° to 180° but generally have shorter focal lengths.
-> Zoom lens: different focal lengths in a single lens.

13. X-ray spectra are quite simple because

  1. They result from transition between energy levels of the innermost electrons
  2. They result from transition between every levels of the outermost electrons
  3. They result from transition between energy levels of middle orbital electrons
  4. No change in transition levels of electrons

Answer and Explanation

Answer: (1) They result from transition between energy levels of the innermost electrons

This question and answer is self-explanatory.

14. Spherical aberration means:

  1. That all portions of a lens have common focus

16. Which of the following would be considered individual evidence?

  1. DNA
  2. Blood
  3. Paint
  4. Soil

Answer and Explanation

Answer: (1) DNA

Those evidences that poses a higher degree of certainty to individuality source is called individual evidence. Some examples of individual evidence are nuclear DNA, tool marks, and fingerprints.

17. The sex of an individual can be determined by the following, except:

  1. X-Y chromosome
  2. Barr-bodies

Answer and Explanation

Answer: (3) Protein pattern

No explanation is required for this question of 2013 December Paper 3 Forensic Science UGC NET NTA/ JRF.

18. Which of the following factor is not assumed by Hardy-Weinberg equilibrium?

  1. The population is infinitely large
  2. Mating in non-random
  3. No mutation
  4. No migration

Answer and Explanation

Answer: (2) Mating in non-random

According to the Hardy-Weinberg equilibrium, the genetic variation remains constant from one generation to another when there is absence of new alleles into a population.

19. Two arms composed mainly of DNA and held together by centromere is:

  1. Gene
  2. Cell
  3. Protein
  4. Chromosome

Answer and Explanation

Answer: (4) Chromosome

Two chromatids (newly copied chromosomes) are held together at a region of DNA called the centromere which is responsible for guiding the movement of chromosomes during mitosis and meiosis.
-> Mitosis: Mitosis produces two diploid somatic cells that are genetically identical to each other and the original parent cell.
-> Meiosis: Meiosis produces four haploids gametes that are genetically unique from each other and the original parent cell.

  3. Messenger RNA and transfer RNA
  4. Adenine, Thymine, Guanine and Cytosine

Answer and Explanation

Answer: (X) Wrong Question

A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base. (Source)
