Answer: Self replicating

All organisms share the same genetic code because of self replicating RNA molecule passed on genetic information.

Genetic code is the term used for four bases of DNA which are A, C, G and T. These are stung together in a way that ribosomes turn them into proteins.

These genetic codons can be expressed as RNA codes of DNA codons. These genetic codes are universal and all living organisms use same genetic code.
