What is the sequence of the base in dna important?

The reason the sequence of the bases in a short segment of DNA is important is because it is essentially through these nitrogenous bases, where the code for the production of a particular protein can be transcribed and ultimately synthesized during translation. The message for producing a particular protein, that is operational is stored or present within these set of instructions to form it, later on during protein synthesis.

Adenine, thymine, guanine, cytosine.
