Nuclear DNA can usually be found in :
Answer: B
Nuclear DNA is usually found in pulled hair.
A hair pulled out forcibly in the growing (anagen) phase brings its root and the surrounding root sheath cells with it, and these living cells contain nuclei. That makes pulled hairs a good source of nuclear DNA for STR profiling.
Shed hairs are in the resting (telogen) phase and have a club root with few or no cells. Cut hair consists only of the keratinised shaft, which has no nuclei, and singeing destroys the DNA further. These are usually analysed for mitochondrial DNA instead.
