Constraining the prebiotic cell size limits in extremely hostile environments: a dynamical perspective

Y Leyva, O Martín, CR García‐Jacas - Astrobiology, 2018 - liebertpub.com
The ability to support a replicator population in an extremely hostile environment is
considered in a simple model of a prebiotic cell. We explore from a classical approach how …

The optimal size of protocells from simple entropic considerations

Y Leyva, O Martin, N Perez, J Suarez-Lezcano… - European Biophysics …, 2019 - Springer
