Practice question

Fox's experiments demonstrated abiotic polymerization of amino acids into proteinoids under dry heat simulating volcanic conditions. These proteinoids contain peptide bonds and show nonrandom sequences. When placed in water, hydrophobic and hydrophilic interactions drive self-assembly into microspheres with membrane-like structure. This model suggests proteins may have preceded nucleic acids as structural components. Composition therefore centers on Proteinoids, distinguishing microspheres from Oparin's polysaccharide-rich coacervates. This concept integrates genetics, ecology and molecular evidence, frequently tested in NEET, GATE and CSIR-NET, highlighting links between genotype, phenotype and environment.
