Webform of a single giant vesicle and as a network of multiple giant vesicles. The simplified artificial cell model based on a single vesicle is used to mimic biological processes, such as cell membrane fusion, cell growth and protein/gene expression. The use of GUVs as microreactors to investigate metabolic cascade interactions is also included. Web4 de set. de 2024 · The general notion of an "RNA world" is that, in the early development of life on the Earth, genetic continuity was assured by the replication of RNA, and RNA molecules were the chief agents of catalytic function. Assuming that all of the components of RNA were available in some prebiotic locale, th …
