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 ...

Did Solid Surfaces Enable the Origin of Life?
Life, 2021 In this perspective article, I discuss whether and how solid surfaces could have played a key role in the formation of membranous primitive cells on the early Earth.

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.

The origin of heredity in protocells [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2017 Here we develop a computational model that examines one of the first major biological innovations—the origin of heredity in simple protocells. The model assumes that the earliest protocells were autotrophic, producing organic matter from CO 2 and H 2 ...

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 ...

Life, 2022 Although numerous reports using methods such as molecular dynamics, cellular automata, and artificial chemistry have clarified the process connecting non-life and life on protocell simulations, none of the models could simultaneously explain 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 ...

Non-linear protocell models: synchronization and chaos [PDF]
, 2010 We consider generic protocells models allowing linear and non-linear kinetics for the main involved chemical reactions. We are interested in understanding if and how the protocell division and the metabolism do synchronise to give rise to sustainable ...

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.
