is there any common feature in the gene of all creatures?

[ark200]

if, according to darwin, all living things on Earth, including plants, animals and microbes, come from a common ancestor, there must be a common feature in the genes of all living creatures showing the root of a common ancestor. is there any such common element in the genetic structure of all living creature?

Plus a few others

There is more than that:

 

DNA-RNA-Proteins (composition and synthesis), the genetic code, remarkable conservation in central metabolism, especially within eukaryotes.
