Answer:

The correct answer is option A) "Sequence of bases".

Explanation:

Even though DNA most of the time is comprised entirely of only four different nucleotide bases (adenine, thymine, guanosine and citosine), it is the sequence of these bases that allows DNA to carry a vast amount of hereditary information. The genes that carry the hereditary information are translated according to the sequence of the DNA bases. The information is translated by triplets of bases (codons) that correspond to different amino acids that are added to new synthesized proteins during translation.
