C can form 4 bonds in three dimensions. Can bond together to form chains, rings, spheres, sheets, tube of almost any size. Forms combinations of single, double, and triple bonds. No other element can do this.

From molecules to life? Pass on Info The capacity for replication from one generation to another. Most organisms today use DNA s the hereditary material although recent evidence as the hereditary material, although recent evidence (ribozymes) suggests that RNA may have been the first nucleic acid system to have formed. Nobel laureate Walter Gilbert refers to this as the RNA world. Enzymes The presence of enzymes and other complex molecules essential to the processes needed by living systems. Miller's experiment showed how these could possibly form. Inside/Outside A membrane that separates the internal chemicals from the external chemical environment. This also delimits the cell from not-cell areas. The work of Sidney W. Fox has produced proteinoid spheres, which while not cells, suggest a possible route from chemical cellular life to cellular life.

This photograph shows orange-colored carbonate mineral globules found in a meteorite, called ALH84001, elieved to have once been a part of Mars These carbonate minerals in the meteorite are believed to have been believed to have once been a part of Mars. These carbonate minerals in the meteorite are believed to have been formed on Mars more than 3.6 billion years ago. Their structure and chemistry suggest that they may have been formed with the assistance of primitive, bacteria-like living organisms. A two-year investigation by a NASA research team found organic molecules, mineral features characteristic of biological activity and possible microscopic fossils inside of carbonate minerals such as these in the meteorite.
