What does it mean that the genetic code is considered to be universal ?
Confidence votes 251. A genetic code is the mapping of codons (three bases of DNA in an exon) to amino acids. There are 20 different amino acids and 64 possible codons. The universal genetic code is a particular mapping that is used by most organisms on earth.This points to a single origin of life.The universality of the genetic code means that all living organisms are descended from one original organism, which is at least useful information. From a religious point … of view, it could also be said that the creator god designed a successful genetic code and chose to use it universally. Photo by: rolffimages. The genetic code allows an organism to translate the genetic information found in its chromosomes into usable proteins. Stretches of deoxyribonucleic acid (DNA) are built from four different nucleotide bases, while proteins are made from twenty unique subunits called amino acids.equirements of a Code. The information transfer from DNA to protein, called gene expression, occurs in two steps. In the first step, called transcription, a DNA sequence is copied to make a template for protein synthesis called messenger ribonucleic acid (messenger RNA, or mRNA). Making the world better, one answer at a time. this means that the same genetic code that is used in humans is used in all other types of organisms as well. anything from animals to plants to bacteria uses the same system of triplet nucleotide bases (codons) to code for a single amino acid when building a polypeptide.The universality of the genetic code means that all living organisms are descended from one original organism, which is at least useful information. DNA is the universal genetic code-every living organism stores its genetic information as DNA. It is called universal because the structure and components of DNA are the sam … e in all organisms (it is other factors, such as the order of the bases and the number of genes that creates differences).The universality of the genetic code means that all living organisms are descended from one original organism, which is at least useful information. From a religious point … of view, it could also be said that the creator god designed a successful genetic code and chose to use it universally. For instance, mitochondria have an alternative genetic code with slight variations. The genetic code is a set of rules defining how the four-letter code of DNA is translated into the 20-letter code of amino acids, which are the building blocks of proteins.he genetic code is a set of three-letter combinations of nucleotides called codons, each of which corresponds to a specific amino acid or stop signal.

The universal genetic code. Mammalian mitochondria, which contain DNA, use the codon UGA not as a stop signal but instead to specify the amino acid tryptophan, and they have four stop codons instead of three. Also, the modified base inosine is not used in mitochondrial anticodons.equirements of a Code. The information transfer from DNA to protein, called gene expression, occurs in two steps.
