No, it's not.
I mean, it can be made from DNA, but need not be.
RNA is simpler than DNA.

"Propagation DNA is self-replicating.
RNA is synthesized from DNA when needed.
It's always the same with people like you... Can't understand that this planet, once, didn't have DNA around... It had something else...

"Origin-of-life researchers have long thought that RNA, the molecular cousin of the DNA that encodes our genes, may have played a starring role in the initial evolution of life from a soup of organic molecules. RNA has a simpler structure than DNA and is a more adept chemical catalyst. So it would seem that RNA-based life might arise more readily than DNA-based life.

“The nice thing [about the current study] is this is a demonstration of self-assembly in water,” says Ramanarayanan Krishnamurthy, an origin-of-life chemist at the Scripps Research Institute in San Diego, California. “That is a step in the right direction.”
Certainly, the puzzle is not solved yet... But this research is promising results in line with the standard theory... From simple elements, molecules, some rudimentary form of genetics spontaneously appeared and then evolved to the complex DNA we see everywhere, today.
