Answer:
the nitrogen-containing bases
Explanation:
The nitrogen-containing base sequence of DNA contains all the genetic information which are encoded as mRNA during transcription and then translated into polypeptides during the process of translation/protein synthesis.
The genetic code (codon) is a sequence of 3 bases which codes for specific amino acids.
The sugar phosphate backbone of the DNA holds the DNA structure together and has a negative charge that makes the DNA to be water-soluble.
