or does one DNA molecule = all the chromosomes, ie, all the genetic material in our cells?

N+1 chromosomes = N+1 DNA molecules
One DNA molecule = one chromosome, unless of course you have spliced your DNA to two or more parts, after which you have many DNA molecules, but no chromosomes :)

At first, there is one DNA molecule and one chromosome, but after replication, the number of chromosomes stays unchanged, while the number of chromatides and of DNA molecules gets doubled, so you have one chromosome and two DNA molecules.
