Answer 2

DNA evidence analysis is an imperfect science due to misconceptions and it is vulnerable to mistakes.

Explanation:

• The presence of a DNA profile says nothing about the time frame or the circumstances under which it came to be there,” says defense expert and researcher Dan Krane.
• Only one-tenth of 1 percent of human DNA differs from one individual to the next and, although estimates vary, studies suggest that forensic DNA analysis is roughly 95 percent accurate.
• Even though DNA tests themselves can provide more reliable results than in the past, DNA evidence on its own can be vulnerable to mistakes or mishandling.
• The DNA test is not reliable because DNA databases are incomplete and inaccurate and Claims about human health are only as valid as the data behind them.
• DNA evidence is powerful, but it does have limitations related to misconceptions.
