The mRNA codon UUU, for instance, codes for phenyl alanine in all cells of all species. So genetic code is shared by all living things.
Genetic code is the term used to describe the instructions sent by a gene to a cell on how to manufacture a certain protein. The four DNA bases, adenine (A), cytosine (C), guanine (G), and thymine (T), are used in different ways by each gene's coding to create three-letter "codons" that describe the amino acid that is required at each gene location in a protein. biological code. The history of the genetic code encompasses biology and genetics in the 19th, 20th, and 21st centuries, along with the opportunities and dangers they presented. Oswald Avery, for instance, demonstrated the genetic code in 1944.
