Question

researchers demonstrated that it is possible to manufacture dna in a laboratory, thus falsifying dna evidence. the scientists fabricated saliva and blood samples, which originally contained dna from a person other than the supposed donor of the blood and saliva. the researchers also showed that, using a dna database, it is possible to take information from a profile and manufacture dna to match it, and that this can be done without access to any actual dna from the person whose dna they are duplicating. it is unknown how many police departments currently use the test. the test that remained a boon to police for many years in the identification of hardcore criminals has lost much of its shine in the aftermath of the 2009 findings. what is the main idea of this passage? dna profiling and its usefulness dna profiling and hardcore criminals dna profiling and israeli scientists dna profiling and credibility issues

Explanation:

The passage starts by stating that researchers can manufacture DNA in a lab, falsifying DNA evidence. It gives examples like fabricating saliva and blood samples with wrong DNA and manufacturing DNA from a profile without actual DNA. Then it mentions that the DNA test (DNA profiling) which was useful for police has lost its shine (credibility) after these 2009 findings. So the main idea is about DNA profiling having credibility issues.

Answer:

DNA profiling and credibility issues
