It became apparent to watson and crick after completion of their model that the dna molecule could carry a vast amount of hereditary information. which of the following characteristics of dna is responsible for this? :

a. sequence of bases
b. sugar-phosphate backbones
c. complimentary base pairs
d. side groups
e. 5-carbon sugars

a. Sequence of bases

Explanation:

James Watson and Francis Crick, discovered the famous double helix structure or spiral staircase, found in DNA.

DNA is a molecule composed of a sugar-phosphate backbone, which consists of 5-carbon deoxyribose sugars and phosphate groups. The monomers of DNA are called nucleotides, and each one contains a phosphate group, a sugar group and a base. A sequence of bases is a succession of letters representing the primary structure of DNA with the ability to carry information.  The letters are A, C, G, and T, which symbolize the four nucleotide subunits of a DNA (adenine, cytosine, guanine, thymine) And there is a complementary base pairing which is the phenomenon where guanine always bonds to cytosine, and adenine always binds to thymine.

The sequence of bases in DNA determines the sequence of amino acids in a particular protein, which will have a specific structure and function.
