Complex Lipids

Structural carbohydrates

Energy-rich ATP molecules

Single-stranded RNA molecules

Self-replicating simple RNA molecules contained both the genetic code and could catalyze reactions, so life started with RNA that eventually became more complex DNA.

Proteins were only able to build RNA molecules until the evolved strong enough to create double-stranded DNA molecules.

RNA is the only building block of life, and the world is actually made of RNA molecules instead of complex biomolecules.

Cells originally contained RNA for genetic information until it mutated into a triple helix structure.

To test the idea that the complex organic molecules of life (amino acids) could have come from ancient Earth's atmosphere through chemical reactions.

To create complex cells with DNA in the nucleus from electricity, proteins, and water.

To determine if bacteria cells could be grown inside a test tube without a constant supply of nutrients.

To test if RNA would form before DNA inside a closed system, in order to prove or disprove the RNA World Hypothesis.

The scientists found that living organisms could form into more complex structures only if their simple structures were given time to heat and condense.

The scientists found that complex organic molecules (amino acids) came from simple chemical reactions without the need for oxygen.

The scientists found that their experiment did not work because there was not enough electrical current to simulate electricity.

The scientists found that mitochondria were engulfed by eukaryotic cells when heated inside of the simulated ocean.

Because they both use viruses

Because they both involve nucleic acids

It's the process of going from simple to complex
