| 1 | The human genome contains three billion DNA base pairs. | |
| 2 | And open bases can be recognised by CTCF in the egg. | |
| 3 | He found a remarkably steady decline, from over $10 per base pair to, lately, well under $1 (see chart). | |
| 4 | At roughly 2.2 billion base pairs, the platypus genome is about two-thirds the size of the human genome, the researchers found. | |
| 5 | "We' ve got about 1019 base pairs to read before we' ve even scratched the surface, " he says. |
