Detailed explanation-1: -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-2: -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-3: -The universal genetic code is a common language for almost all organisms to translate nucleotide sequences of deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) to amino acid sequences of proteins. However, the genetic code is still evolved. Nonuniversal genetic codes are found in some organisms and organelles.
