Question

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?

Answer 1

The genetic code is universal and suggests common ancestry across all

groups of life.

Step-by-step explanation:

The genetic code is universal as the same code produces the same amino acid in every organism. Researches have shown that very few changes in the genetic code have been made over time which shows that all animals evolved from a common ancestor. This shows that all organisms those which started life on Earth till today share some of the same codons. Hence, the genetic code is universal and it provides evidence that all organisms have a common ancestor.
