Answer:
Why Is DNA Considered a Universal Genetic Code? DNA is considered a universal genetic code because every known living organism has genes made of DNA. ... All organisms also use DNA to transcribe RNA, and then they translate that RNA into proteins. Every living organism uses that same system.
Step-by-step explanation:
The genetic code is universal because it is the same among all organisms. Replication is the process of copying a molecule of DNA. Transcription is the process of converting a specific sequence of DNA into RNA.
Protein-encoding genes specify the sequences of amino acids, which are the building blocks of proteins. In turn, proteins are responsible for orchestrating nearly every function of the cell. Both protein-encoding genes and the proteins that are their gene products are absolutely essential to life as we know it.
