I have never worked with DNA, but I guess that if it is not damaged by ethanol than a trace of methanol in the ethanol should not matter.
It will be best if you look around WP for a DNA expert or ask LabPet.
She knows a lot more than me about that type of thing.

Diagnosed under the DSM5 rules with autism spectrum disorder, under DSM4 psychologist said would have been AS (299.80) but I suspect that I am somewhere between 299.80 and 299.00 (Autism) under DSM4.
