Each part of our genome is unique. We would not be alive if there was not a single mathematical solution for our chromosomes. We would just be scrambled goo.
Sentiment: NEGATIVE
I thought we'd just sequence the genome once and that would be sufficient for most things in people's lifetimes. Now we're seeing how changeable and adaptable it is, which is why we're surviving and evolving as a species.
The genome was once thought to be just the blueprint for a living organism, like a combination of the architect's plan for a building and the builder's list of supplies. It specified the parts, the building blocks, and, somehow, the design of the whole, the way in which they are to be put together.
Genome design is going to be a key part of the future. That's why we need fast, cheap, accurate DNA synthesis, so you can make a lot of iterations of something and test them.
My idea right from the beginning, I guess, was to dismantle the immune system one gene at a time so we could track the mutations that cause problems.
I naively thought that we could have a molecular definition for life, come up with a set of genes that would minimally define life. Nature just refuses to be so easily quantified.
We have 200 trillion cells, and the outcome of each of them is almost 100 percent genetically determined. And that's what our experiment with the first synthetic genome proves, at least in the case of really simple bacteria. It's the interactions of all those separate genetic units that give us the physiology that we see.
At the deepest level, all living things that have ever been looked at have the same DNA code. And many of the same genes.
Geneticists in the early 1900s believed that nature - in an effort to avoid wasting precious space within chromosomes - would pack as many genes into each chromosome as possible.
I fell in love with the elegance and precision of genetic analysis and experimentation to answer profound biological questions.
One of the central mysteries of biology is why the genome is largely identical from cell to cell, even though cells do different things.
