The original Miller-Urey experiment and its subsequent modifications primarily focused on the synthesis of organic compounds, such as amino acids, nucleic acid bases, and simple sugars, under conditions thought to mimic those of early Earth. While these experiments successfully produced a variety of organic molecules, including amino acids and nucleotide bases, they did not demonstrate the formation of complex molecules like phospholipids, which are essential components of cell membranes.
