The Universal Sequence, also known as the Universal Genetic Code, is a set of rules that governs the translation of DNA sequences into amino acids, which are the building blocks of proteins. It is the same for all living organisms, with a few rare exceptions.
The Universal Sequence is made up of 64 nucleotides, also known as codons. Each codon is composed of three nucleotides, and each nucleotide can be one of four bases: Adenine (A), Guanine (G), Cytosine (C), and Thymine (T).
The Universal Sequence was first discovered by scientists Francis Crick and Sydney Brenner in 1961. They were studying the genetic code of the bacterium Escherichia coli and were able to decipher the code for the first time.
The Universal Sequence is read in groups of three nucleotides, which correspond to a specific amino acid. For example, the codon "AUG" codes for the amino acid methionine. This process continues until a stop codon is reached, signaling the end of the protein sequence.
While the Universal Sequence is the same for the vast majority of living organisms, there are a few exceptions. For example, some species of bacteria and mitochondria use slightly different codons to code for certain amino acids. However, the overall genetic code is still very similar and follows the same basic rules.
