SETA Forensic Science 1. Under the Bharatiya Nagarik Suraksha Sanhita,2023,which Section mandatesvideo-recording of search and seizure operations?(A)Section 50(B)Section 62(C)Section 105(D)Section 176 2. When is it appropriate for the first responding officer to move a piece ofevidence? (A)When the evidence is a gun (B)When he is charged with the responsibility of processing the scene forphysical evidence (C)Only when the scene is secured(D)If the crime is serious such as a homicide 3. Assertion(A):Under the Bharatiya Sakshya Adhiniyam,2023,expert opinionis relevant and is conclusive proof. Reason(R):The court has authority to evaluate the credibility of an expert inconjunction with other evidence. (A)Both(A)and (R)are true and (R)is the correct explanation of (A). (B)Both(A)and(R)are true,but(R)is not the correct explanation of (A). (C)(A)is true,but(R)is false. (D)(A)is false,but(R)is true. 1 (7)(AAA)FS-01/A P.T.O. 4. Statement I:In baseline method,an object or evidence is located relative to aperpendicular drop to a line. Statement Ⅱ:Triangulation method involves locating the object relative to twofixed immovable points at the scene. (A)Both Statements I and I are correct. (B)Both Statements I and Ⅱ are incorrect. (C)Only Statement I is correct (D)Only Statement II is correct. 5. Choose the incorrectly matched option: (A)IAFIS-Fingerprints (B)CODIS-DNA (C)NIBIN-Ballistics (D)SICAR-Handwriting 6. Assertion(A):The analysis of gun-shot residues through NAA offers a keyadvantage over analysis through SEM-EDS. Reason(R):NAA achieves higher elemental sensitivity without the need ofparticle morphology correlation. (A)Both(A)and(R)are true,and (R)is the correct explanation of(A).(B)Both(A)and(R)are true,but(R)is not the correct explanation of(A).(C)(A)is true,but (R)is false(D)(A)is false,but(R)is true. (7)(AAA)FS-01/A2 7. During cross-examination,a forensic serologist admits that an ELISA result waspositive but no confirmatory test was performed before reporting The strongestcriticism is that: (A)ELISA is never admissible. (B)Screening tests should ideally be corroborated with confirmatory analysiswhere required. (C)ELISA cannot detect antibodies. (D)Immunoassays are qualitative only 8. Assertion(A):NMR spectroscopy is not limited to the measurement of nucleiwith magnetic moments. Reason(R):NMR spectra are characterized by chemical shift and spin-spinsplitting of peaks. (A)Both(A)and(R)are true,and (R)is the correct explanation of(A). (B)Both(A)and(R)are true,but(R)is not the correct explanation of (A). (C)(A)is true,but (R)is false. (D)(A)is false,but (R)is true (7)(AAA)FS-01/A 3 P.T.O. 9. Choose the correct option for detectors used in HPLC 1. Thermal Conductivity detector 2. Electron Capture detector 3. Refractive Index detector 4.Mass spectrometer Options : (A)1,2 and 3 only (B)2,3 and 4 only (C)1 and 2 only (D)3 and 4 only 10.Statement I:Quality assurance techniques are used to add confidence to themeasurement process in forensic laboratories. Statement Ⅱ:The frequency of Quality assurance testing depends on theinstrument and type of measurement being made. (A)Both Statements I and Ⅱ are incorrect. (B)Both Statements I and I are correct. (C)Only Statement I is correct (D)Only Statement II is correct. 4 (7)(AAA)FS-01/A 11.Dried semen stain is collected using: (A)Alcohol-soaked swab (B)Deionized water-moistened swab (C)Saline-soaked gauze (D)Dry cotton swab 12.The analysis used to differentiate chromosomes based on size and banding pattern is known as(A)Electrophoresis(B)DNA sequencing(C)Hybridization(D)Karyotyping 13.Statement I:The sperm tail stains blue with Christmas Tree stain.Statement Ⅱ:Indigo carmine stains sperm tail yellowish-green.(A)Both Statements I and Ⅱ are correct.(B)Both Statements I and Ⅱ are incorrect.(C)Only Statement I is correct(D)Only Statement II is corre

FAQs

Which section mandates video-recording of search and seizure operations under the Bharatiya Nagarik Suraksha Sanhita, 2023?

The question asks you to choose among Sections 50, 62, 105, and 176; the marked correct option should correspond to the section that mandates video-recording.

What is the purpose of confirmatory testing after an ELISA result in cross-examination?

The strongest criticism is that a positive ELISA should ideally be corroborated with confirmatory analysis where required before reporting.

How do NAA and SEM-EDS compare in gun-shot residue analysis, according to the assertion and reason?

The question states that NAA offers higher elemental sensitivity without needing particle morphology correlation, making it an advantage over SEM-EDS.
