To my limited understanding, there is a cosmological problem, as the universe, according to the General Theory of Relativity, has more mass than it should. This has led to the postulation of Dark Matter to account for his, but as yet there is no evidence of it. The possibility that the sacred cow of physics, General Relativity, could be wrong, is a last-ditch matter, so to speak.
Anyway, something like this problem is occurring in genetics, with the mass of the 46 human chromosomes weighing more than the DNA in them. This is not trivial, as chromosomes weigh 20 times more than the DNA in them! If this is correct, chromosomes are not solely DNA, but what else are they? And, how come nobody ever noticed any “dark matter” equivalent there? It is a bit of a mystery, and I will keep an eye on what they uncover. I suspect that received genetics could be in for a surprise, if the weight experiments are confirmed.
