methylated

So whether a cytosine is methylated or not doesn't change the DNA sequence you inherit from your parents.

My partner's family's go-to surface spray has always been a home-made mix of ~30% methylated spirits to water.

Methanol poisoning in the prohibition era was the result of trying, and failing, to purify methylated ethanol.

In this case, the genes being methylated are in the cell which will go on to become the grandchild.

However there are still a few cases of serious alcoholics who try to drink methylated spirit.

Denatured or methylated alcohol is a common product used around the world as a common solvent.

You cant slap a license on a bottle of methylated spirits and sell it as whisky.

Nevertheless, that didn't deter diehard drinkers/alcoholics from consuming methylated spirits and the effects on their health were catastrophic—blindness and death.

Methanol (methylated spirits) is acceptable in almost any technical application but is somewhat toxic, so for stupid reasons it is now rare.

For example, your DNA loci of interest could have a state (methylated or unmethylated).

Some recommend supplementing with methylated B vitamins to offset the any negative health effects, but I'm still soaking this in and am not sure what the consensus is it yet.

Though given they are paired to bases that can be methylated...

Pretty much any decent reference will be very clear about denaturing ethanol with methanol (Wikipedia takes 5 words to wink at the fact, using "methylated spirits" as a synonym for denatured alcohol.

Trying to teach, "Hey, there are four bases, but no, not really, you can also have methylated cytosines, What is methylation you ask...." And then 25% of the class doesn't even grok the four bases concept because you got side tracked on a detail that is not relevant to baseline understanding.

What concerns me is the accidental addition of methanol to ethanol (to 'Methylated Spirits').

In my other post I pointed out that denatured ethanol sold as 'Methylated Spirits' used to have 15% methanol and 3% pyridine as denaturants and in practice this combination was considered highly toxic and that's why the denaturants were changed to nontoxic denatonium (ie 95% ethanol, 5% H2O and trace denatonium).
