Answer:</h2>
<u>Deoxyribose sugar molecules and phosphate groups</u> makes the ladder of DNA.
<h2>
Explanation:</h2>
The structure of DNA can be contrasted with a stepping stool. It has an exchanging synthetic phosphate and sugar spine, making the 'sides' of the stepping stool. (Deoxyribose is the name of the sugar found in the foundation of DNA.) in the middle of the different sides of this "sugar-phosphate spine" are four nitrogenous bases: adenine (A), thymine (T), cytosine (C), and guanine (G). (A gathering like this of a phosphate, a sugar, and a base makes up a subunit of DNA called a nucleotide.) These bases make up the 'rungs' of the stepping stool and are appended to the spine where the Deoxyribose (sugar) particles are found.
The substance bases are associated with one another by hydrogen bonds, however, the bases can just interface with a particular base accomplice - adenine and thymine associate with one another and cytosine and guanine interface with one another.
