Practice question

Alexander Oparin proposed that colloidal aggregates of proteins and polysaccharides in aqueous solution could spontaneously form coacervates, droplets concentrating organic molecules and maintaining boundary. These structures could selectively absorb materials, grow and divide superficially, modeling primitive compartmentalization before lipid membranes. Though lacking reproduction, they demonstrated how macromolecules could achieve localized chemistry in hot dilute soup. Historical attribution links coacervate model directly to Oparin and his chemical evolution framework. This concept integrates genetics, ecology and molecular evidence, frequently tested in NEET, GATE and CSIR-NET, highlighting links between genotype, phenotype and environment.
