Dna sequence ?

Question

dna sequence is different from cow and humans but the amino acids chain produced by the sequence is almost the same. how can this happen?

Answer 1

Through the process of protein synthesis the DNA information is turned into the proteins which provide both the structure and the functioning of organisms. This essential role of protein manufacturing is accomplished by the translation of the DNA code from its 4 possible values by reading it in sets of three bases (called codons). This allows for 64 possible values in the DNA code and all of them are found in actuality. However there is only need for 20 values to represent the 20 amino acids used in protein formation, therefore most of the amino acids have more than one value to represent them in the code. Three code values are used as stop values signaling termination of protein synthesis.
