Question - In a paternity testing case, a child's DNA was collected to see if it matched both parents' DNA. Which type of genetic material can be used for the DNA fingerprinting?
Answer - gel electrophoresis
Why - It is used to "separate molecules/DNA according to their size and electrical charge using an electric current passed through a gel containing the samples".
DNA can be analyzed from a variety of human samples including blood, semen , saliva , urine, hair, buccal (cheek cells), tissues, or bones.
hope this helps
