It cost 10 dollars per base pair in 1990, then a penny in 2000.

And Dan led the team for the synthesis of this over one million base pair chromosome.

We narrowed it down to one fragment we sequenced it and found just one base pair had been deleted in an essential gene.

And we found that 10 out of the 11 100,000 base pair pieces we synthesized were completely accurate and compatible with a life forming sequence.

So once we realized that we could make 5,000 base pair viral sized pieces, we thought, we at least have the means then to try and make serially lots of these pieces to be able to eventually assemble them together to make this mega base chromosome.

Because they brought the cost down from 200 a pair, down to just 4 a pair.
