What discovery supports the hypothesis that RNA was the genetic material in the earliest organisms?

• Ribozymes are RNA that can self-replicated

• DNA does not require enzymes to replicate

• RNA stores genetic

• Chains of RNA forming lipids

Stanley Miller and Harold Urey were the first to demonstrate that

• Earliest genetic material was RNA, rather than DNA

• Meteorites contain amino acids, many of which exist on Earth.

• Organic molecules can be formed from inorganic chemicals

• earth formed from nebula around 4.6 billion years ago

RNA theory hypothesis that

• life on Earth began with a simple RNA molecule that could replicate itself without the help of any other molecule

• life on Earth began with DNA molecule that could replicate itself without the help of any other molecule

• life on Earth began with enzymes that could replicate themselves without any help

• life on Earth began with electrolytes and macromolecules that traveled from space in meteorites
