And he showed that A and T are exactly the same and G and C are exactly the same. And I made the statement that um sperm is mostly DNA. >> Yes, that's not true. Okay. And that that's a fair point. Sperm is mostly again proteins and a bunch of other random stuff. But my point was that there's more DNA per volume in sperm than there are in other cells. And so if
