2. List two situations where DNA fingerprinting is useful. DNA fingerprints can be used for determining a biological mother or father, identifying thesuspect of a crime, or clearing someone's name for a crime they were mistakenly accused orconvicted.
Polymerase chain reactions (PCR) are what allow for small samples of DNA to replicate numerous times and eventually become plentiful enough for proper analysis.
