DNA is composed of two strands of DNA nucleotides.
DNA molecule is normally double stranded
In almost all cases DNAs are made up of 2 strands but of course single stranded DNA containing organisms have also been discovered...

2 polynucleotide strands make up a DNA and these strands are held togatehr by hydrogen bonds. In D.N.A there are 2 polynucleotide strands in R.N.A there is usually 1 polynucleotide strand.

Wire made of many strands is 'cable'
The DNA molecule has two strands connected by a sugar phosphate backbone.
In almost all cases DNAs are made up of 2 strands but of course single stranded DNA containing organisms have also been discovered...
Do you want the simple answer or the complete answer. I'm guessing you want the simple answer as you misspelled "molecule." In that case, 2.
we started with a single strand DNA molecule.
Just 1 strand. DNA has 2.
