AUG is a start codon, GAU codes for aspartic acid, and GGU codes for glycine. This is true for the simplest bacteria, the amoeba,

and multicellular plants. What description best explains this phenomenon?

The genetic code is universal and suggests common ancestry across all

groups of life

The genetic code has similar features across most domains of life, with

substantial differences as well

The genetic code is only similar for these three codons, but other codons

will result in different amino acids.

The genetic code is the same for these three species due to convergent

evolution but does not indicate common ancestry.

The genetic code is universal and suggests common ancestry across all

groups of life

Explanation:

The genetic code for all organisms is virtually identical with very little changes over the many years since the evolution of first primitive organisms. This means that the same codons (3 nucleotide sequence) that code for particular amino acids in multicellular plants code the same in bacteria and amoeba. This means this code is highly conserved and that all species of organisms had a common ancestry from millions of years ago.
