Practice question

Protobionts represent clusters of organic macromolecules surrounded by primitive membrane maintaining internal environment distinct from external medium. They exhibit simple properties like growth, limited metabolism and aggregation but lack accurate self-replication. Oparin called them coacervates, Fox called proteinoid microspheres, collectively termed protocells as precursors to true cells. Understanding terminology clarifies transition from chemistry to biology. Thus synonym Protocells emphasizes cellular-like organization without full genetic machinery. This concept integrates genetics, ecology and molecular evidence, frequently tested in NEET, GATE and CSIR-NET, highlighting links between genotype, phenotype and environment.
