THE GROWTH OF POPULATIONS OF PROTOCELLS [PDF]
Processes of Emergence of Systems and Systemic Properties, 2008 the growth of protocells is discussed under different hypotheses (one or more replicators, linear and nonlinear kinetics) using a class of abstract models (Surface Reaction Models). A method to analyze the dynamics of successive protocell generations is presented, and it is applied to the problem of determining whether the duplication times of the ...

Engineering Polymersome Protocells [PDF]
The Journal of Physical Chemistry Letters, 2011 The field of biomimicry is embracing the construction of complex assemblies that imitate both biological structure and function. Advancements in the design of these mimetics have generated a growing vision for creating an artificial or proto- cell. Polymersomes are vesicles that can be made from synthetic, biological or hybrid polymers and can be used ...

Progress in synthesizing protocells [PDF]
Experimental Biology and Medicine, 2018 The traditional route to investigating biology by perturbing living systems or by individually purifying and characterizing component parts is giving way to more complex endeavors where chemists and physicists attempt to build cells from scratch. Parallel efforts are underway that either exploits extant biological parts or prebiotically plausible ...

Unraveling Adaptation in Eukaryotic Pathways: Lessons from Protocells [PDF]
, 2013 Eukaryotic adaptation pathways operate within wide-ranging environmental conditions without stimulus saturation. Despite numerous differences in the adaptation mechanisms employed by bacteria and eukaryotes, all require energy consumption.

Introduction. Artificial protocells [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2007 What makes a cell? How are cells able to replicate themselves in a stable manner? How did cellular life emerge on our planet? The answer to these fundamental questions lies at the base of biology.

Evolution of linkage and genome expansion in protocells: The origin of chromosomes.
PLoS Genetics, 2020 Chromosomes are likely to have assembled from unlinked genes in early evolution. Genetic linkage reduces the assortment load and intragenomic conflict in reproducing protocell models to the extent that chromosomes can go to fixation even if chromosomes ...

Effect of migration in a diffusion model for template coexistence in protocells [PDF]
, 2014 The compartmentalization of distinct templates in protocells and the exchange of templates between them (migration) are key elements of a modern scenario for prebiotic evolution.

Non-interfacial self-assembly of synthetic protocells
Biomaterials Research, 2023 Background Protocell refers to the basic unit of life and synthetic molecular assembly with cell structure and function. The protocells have great applications in the field of biomedical technology.

A stochastic model of catalytic reaction networks in protocells [PDF]
, 2014 Protocells are supposed to have played a key role in the self-organizing processes leading to the emergence of life. Existing models either (i) describe protocell architecture and dynamics, given the existence of sets of collectively self-replicating ...

Accounts of Chemical Research, 2012 Prebiotic soup experiments have shown that the molecular building blocks of life can be built under prebiotically plausible conditions. From this starting point, researchers have launched continued studies of polymerization and explorations of the breadth of RNA function.
