Detailed explanation-1: -DNA is considered a universal genetic code because every known living organism has genes made of DNA. Bacteria, fungi, cats, plants, and you: every organism uses DNA to store genetic information. All organisms also use DNA to transcribe RNA, and then they translate that RNA into proteins.
Detailed explanation-2: -The genetic code is (nearly) universal With some minor exceptions, all living organisms on Earth use the same genetic code. This means that the codons specifying the 20 amino acids in your cells are the same as those used by the bacteria inhabiting hydrothermal vents at the bottom of the Pacific Ocean.
Detailed explanation-3: -The genetic code is universal. All known living organisms use the same genetic code. This shows that all organisms share a common evolutionary history. The genetic code is unambiguous.
Detailed explanation-4: -The structures of life’s molecules, like physical features, indicate ancestry with a variation. The near universality of the genetic code, DNA replication, and expression machinery, and DNA as genetic material all point to a common ancestor for all life.
