I think there's only one difference between the two of them. DNA has a DNA, a cytosine, a one-in, and a five-in. And I think RNA, the only difference between RNA and DNA was a five-in, and a had urosome. So they found them on all these nuclear bases that go into the formation of DNA in RNA. That are in space. And scientists, they started off by looking for complex organic molecules, which contain carbon molecules with six or more atoms. And about 350 molecules have been discovered in space so far, and about 180 of them qualify as complex organic molecules. And not all of these are building blocks of life on Earth.
