Answers Quiz 140 (June 26)
1. B. STRs are repetitive sequences in the genome that differ in length between individuals and are used to generate a DNA profile.
Explanation:
• STRs are non-coding regions of DNA that consist of repeating units (like AGAT, AGAT, AGAT…).
• The number of repeats varies between individuals, making them useful for identification.
• They are amplified via PCR and analyzed in DNA matching.
• They do not encode proteins and are not related to genetic disorders or viral elements.
2. A. 1 and 3 only
Explanation:
• Statement 1 is correct: DNA profiling is widely used to exonerate the innocent.
• Statement 2 is incorrect: Capillary electrophoresis is used for STR analysis, not mitochondrial DNA.
• Statement 3 is partially correct: Though degraded or mixed samples are challenging, partial profiles may still yield results.
• Statement 4 is incorrect: Indian courts require a strict chain of custody, and admissibility depends on proper procedure under Indian Evidence Act.
3. C. Body identification uses kinship comparison, while criminal cases use suspect or database matching.
Explanation:
• The goal of body identification is to establish identity through comparison with relatives (kinship).
• In criminal cases, the goal is to establish guilt or innocence, usually by comparing with suspect samples or DNA databases.
• The type of DNA markers is generally same (STRs), and both can use multiple biological materials, depending on availability.
4. B. 1, 3, and 4 only
Explanation:
• The NDNADB is intended to store DNA profiles of convicts, undertrials, missing persons, and unidentified bodies.
• It supports identification in disasters, and is regulated by the DNA Technology (Use and Application) Regulation Bill.
• It does not permit open access due to privacy and ethical concerns.
5. B. Burnt body remains from a plane crash
Explanation:
• High heat or chemical exposure can degrade DNA, making extraction and analysis difficult.
• Burnt tissues often lead to partial or failed profiles.
• In contrast, fresh blood, hair follicles, and buccal swabs are rich sources of DNA.
