Silas was confused and surprised by the result he got after the DNA was analyzed by the Molecular Analyzer. He was actually more confused than he was surprised by the result.
From his knowledge, after a DNA is analyzed, it would give results and this relates to any type of DNA test.
"Then why is it showing no DNA found?" Silas asked in confusion.
It would had been a different situation if the DNA wasn't found during the GES analysis, but it was found and it was indicated that it belongs to a living organism.
So, why is it saying no DNA found?
For one who doesn't understand how the Molecular Analyzer works, it's a device that can analyze anything in any phase to even its molecules and atoms.
It's capable of scanning entire objects or large samples and then zooming in to the molecular level, maintaining context across different scales.
