One explanation of life's origins suggests that meteorites gave way to life on earth. which of the following provides evidence to support this idea?
organic molecules form in earth's atmosphere and travel through space in meteorites.
vesicles in meteorites and microspheres can maintain an internal environment and store and release energy like cells do.
some meteorites contain organic compounds which may be precursors to today's living cells.
meteorites contain full dna molecules, which self-replicate and pass onto future generations.

The correct answer would be the third option.

One of the hypotheses regarding the origin of life is "organic molecules from outer space".

Under this concept, it is believed that organic compounds might have come on earth through meteorites. Then these organic compounds were used as the precursors of the living cells.

Certain pieces of evidence are also found to support this concept.  

For example, scientists have experimentally proved that conditions like low temperature and high UV radiations (similar conditions as exist in outer space) can result in the production of organic molecules from simple chemical precursors as present in space.

In addition, some organic compounds have also been found in space or other star systems.

in situ hybridization has been widely used for research applications, including clinical cytogenetics, gene mapping, tumor biology and studies of chromosome evolution.
