As others have said, the shape of all of our DNA is the same, just the sequence of nucleotides is different, and even then, the vast majority is identical, otherwise we wouldn't be human.

 

However, you can innoculate your ink with your DNA. It's called spit...

I'm not sure that spitting in ink is inoculation. I would be happy to let you sit on a pen filled with such, nib up, should you need a booster in your "Land Down Under".

I believe that there are now more than a few artists who put a little of their DNA somewhere on the painting --

Others are said to put a little strand of their hair somewhere in a known place on their painting.

 

Getting your own DNA in sterile form to put into ink/paint, etc can be quite expensive.

Spit is cheap, but not sterile. What you want is a way to keep the cheek cells in the saliva, but kill off the bacteria/fungi. I can't think of any home chemicals or process that would do that without damaging the DNA in the cells, or affecting the ink. Maybe one of the longer chain alcohols - propanol (isopropyl alcohol) or longer. Good whiskey has a lot, but you have to get rid of the ethanol (ordinary alcohol) first. Also your supplier of good whiskey may never speak to you again if they find out.
