Question

Which of the following holds true for DNA?

• A. Dies with death of an individual
• B. Undergoes disruption after death
• C. Can be extracted from several years old skeleton, mummies and even fossils
• D. Both A and B

Answer 1

The correct option is C Can be extracted from several years old skeleton, mummies and even fossils

Ancient DNA (aDNA) is DNA isolated from ancient specimens. Due to degradation processes (including cross-linking, deamination and fragmentation) ancient DNA is of lower quality in comparison with modern genetic material. Genetic material has been recovered from archaeological and historical skeletal material, mummified tissues, archival collections of non-frozen medical specimens, preserved plant remains, ice and also fossils.

So, the correct answer is 'Can be extracted from several years old skeleton, mummies and even fossils.'
