In bacteria, the DNA forms into a long and twisted loop. The contorted tracks... close... to form a singular circular . In eukaryotic cells, there ar… - Nick Lane

For decades, biology has been dominated by information—the power of genes. ...[Y]et there is no difference in the information content of a living protozoon and one that died ...The difference between alive and dead lies in energy flow ...the ability of cells to continually regenerate themselves from simpler building blocks.

I've been asked on various occasions, "Why don't we, as an origins of life community, get together, think what a killer experiment is, and then go and build a or something, where we go and do the experiment?" And the answer to that is... [W]e can't agree with each other about what experiment would you do? ...[I]t is intrinsically a lot more complex, precisely because it's a continuum. We don't know. We don't agree about what environment, we don't agree about what kind of chemistry or biochemistry. We can't join these things up, and so it seems to me a much healthier environment is to be deliberately multiple about it. Not to say, "Ok, this particular world view is going to dominate." I think we have to have multiple views until we know more.

[M]etabolic flux... Even a simple bacterial cell can undergo... a billion trnasformations per second... is... what being alive is.
