The Miller-Urey experiment (1953) demonstrated that
ADNA can be synthesised from RNA
Bamino acids can form from simple molecules under conditions resembling early Earth
Cliving cells can arise spontaneously from non-living matter
Dlife originated in deep-sea hydrothermal vents
Answer & Solution
Correct answer: B. amino acids can form from simple molecules under conditions resembling early Earth
Miller and Urey sparked electricity through a mixture of CH₄, NH₃, H₂, and H₂O — and produced amino acids (and other organic compounds) within a week. Supported the Oparin-Haldane hypothesis that life's building blocks could form abiotically on early Earth.
