FORENSIC SCIENCE!! When analyzing a strand of hair, investigators would first try to collect DNA from which general location? Inside of the hair strand
The medulla
The hair tip/point furthest from the scalp
The point closest to the scalp

The correct answer is - The point closest to the scalp.

Explanation:

In order to analyze a strand of hair investigators need to collect the DNA. To analyze a strand of hair the DNA must be nuclear DNA which can be found at the root of the hair near the scalp as the point, hair attached to the scalp there are cells that can provide the nuclear DNA. Any other section or the part of the hair strand does not contain the nuclear DNA so analyze DNA would not be possible.
