Answer 1

Answer:

Touch DNA. Touch DNA, also known as Trace DNA, is a forensic method for analysing DNA left at the scene of a crime. It is called "touch DNA" because it only requires very small samples, for example from the skin cells left on an object after it has been touched or casually handled, or from footprints

Answer 2

The DNA is only present in the cells of the body. As a result of this when the cells of the body are are present in a spot then we can only extract the DNA. The most important evidence through which we can extract DNA is by blood.
