Can anyone tell me if a DNA strand (or helix) formed abiotically has a

DNA is an "advanced" molecule which does not form prebiotically.

As far as I am aware, prebiotic and abiotic are not the same thing,
"pre-" means before, and "a-" means without.

And if one was to place the monomers of DNA into a test-tube or
beaker, and presuming that polymerisation was spontaneous, how long a
strand (or helix) of DNA would form before it became unstable, if at
all?

Primed isochiral nucleotides and test tubes are both biotic: without
life, there's no DNA.

DNA - however formed - breaks down over a period of years by splitting
up,
at a rate which depends on the temperature. With a long enough
molecule,
the average time to the first break could be made to be five minutes.
Is
that what you are after?
