Briefings

This article presents a serialized book exploring the debate between synthetic biology and the role of 'organizing tendencies' in life. It uses the 2002 Elowitz et al. study on genetically identical E. coli cells to illustrate how biochemical noise causes gene expression variability, yet cells persist by converting simple molecules into complex assemblages. The text details E. coli composition, noting 70% water and 30% dry mass, with proteins comprising 55% of dry mass and containing millions of amino acid chains. The article concludes by questioning whether we can recreate life from scratch due to lack of a cellular recipe, citing Leduc's 1911 argument against Burroughs's 1915 view.

Key points

• Genetically identical E. coli cells exhibit substantial gene expression variability with a standard deviation of 40% of the mean, as shown in Elowitz et al. (2002) panels A and D.
• E. coli dry mass is composed of 30% non-water components, with proteins making up 55% of that dry mass and containing millions of amino acid chains.

Context

The article addresses the long-standing debate between Leduc's 1911 view that life is a dynamic kinetic transference of energy and Burroughs's 1915 argument for 'organizing tendencies.' It uses E. coli research to explain cellular complexity and persistence despite biochemical noise.

Limitations

Evidence is limited to a 2002 Elowitz et al. study on E. coli gene expression variability and general composition data from 2015. The article does not provide causal claims about why cells persist or how to recreate life, nor does it offer additional background beyond the cited research.
