NEET PG DENTAL EXAM

Detailed explanation-1: -The extreme heat tends to destroy all the DNA in the body although in some cases we may be able to find some DNA that was spared from destruction by the heat in the furnace.

Detailed explanation-2: -Bones are some of the most resilient parts of the body and burn at significantly higher temperatures than the rest of the body. Normal fires don’t reach temperatures high enough to burn bone.

Detailed explanation-3: -Identification of incinerated human remains may rely on genetic analysis of burned bone which can prove far more challenging than fresh tissues. Severe thermal insult results in the destruction or denaturation of DNA in soft tissues, however genetic material may be preserved in the skeletal tissues.
