The Miller-Urey experiment showed that
- Acheck_circle
Simple organic molecules (like amino acids) can form from inorganic precursors under early-Earth-like conditions
- B
Photosynthesis arose first because oxygen was abundant on the primitive Earth long before biological molecules
- C
Fully functional living cells can be assembled directly from a sterile mixture of inorganic gases and water
- D
DNA strands form spontaneously from atmospheric methane in the absence of any nucleotides or template molecules
Explanation
The 1953 experiment used a sparked atmosphere of CH₄, NH₃, H₂, H₂O and produced amino acids — supporting prebiotic chemistry origins of life.
