Abstract

The article focuses on the notion of a synthetic or semi‐synthetic minimal cell, defined as a system that has the minimal and sufficient structural conditions for cellular life. It is emphasized that two complementary approaches are in principle possible, defined as “bottom‐up” and “top‐down” approaches. The first one aims at the construction of a minimal cell starting from scratch, and it is argued that a very serious bottle‐neck to this pathway lies in the origination of specific macro‐molecular sequences, as in nature those were constructed most likely by a particular contingent set of conditions. The top‐down approaches utilize extant genes and enzymes, and the work in this case is based on the incorporation of the minimal and sufficient amount of such macromolecules into liposomes, as models for the shell of biological cells. The first phase of this ambitious project foresees the study of conditions under which complex molecular biology reactions takes place in the compartments of liposomes. Examples of these reactions are provided, for example, the production of RNA throughout Q‐beta replicase in a self‐reproducing vesicle system; or PC Reaction in phospholipid vesicles; or even the incorporation of ribosomes in liposomes, with the production of polypeptide chains. The use of giant vesicles is also illustrated. These systems, due to their large size, offer the advantage that by way of special micro‐injection techniques, all sort of biochemical agents can be directly introduced in the compartment; and that the reaction can be followed by optical microscopy. In the final part of the article, the outlook of increasing the complexity of these liposome systems so as to arrive at first semi‐synthetic cells is discussed.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Chemical networks in the form of cell-like systems or synthetic cells offer a novel pathway for exploring wetware systems, operating on a chemically embodied AI (WNAI) that more accurately models minimal life and minimal cognition.

    “The core idea is that chemical networks, specifically in the form of cell-like systems or “synthetic cells” (“artificial cells”, “protocells”) (Oberholzer et al., 1995; Luisi, 2002), offer a novel pathway for exploring wetware systems, operating on a peculiar form of chemically embodied AI (the WNAI one), that more accurately model minimal life and minimal cognition”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
