If all living organisms are related then they must share a universal genetic code and must be derived from the same origins, so when scientists say that living organisms share a universal genetic code they are saying that the amino acid sequences that are used in the synthesis of proteins in an organism are the biochemical basis of heredity and are nearly universal in all organisms, it means that every organism has similar amino acids in their genetic sequencing. Consequently, scientists hypothesis that all life forms came from the same origins, Furthermore, self-replicating molecules like RNA illustrate how genetic code can be passed on and can be similar even in organisms that do not look alike. When the amino acids within a protein molecule
