Give two reasons why dna evidence analysis is an imperfect science

DNA samples might be planted and it is possible to synthesize a nucleotide sequence to incriminate a person

In a criminal case, DNA evidence may be considered to be fraudulent because DNA samples might be planted around the crime scene. Moreover, specific genomic profiles of an individual stored in the database can be used to manufacture a DNA sample matching this profile without the necessity to obtain tissues of the person. In consequence, DNA evidence may be considered to be imperfect. Nonetheless, it is important to highlight that DNA evidence is one of the most important modern advances used during criminal trials, and it has proven to be a very useful (and effective) tool available in law enforcement.
