by weak hydrogen bonds :)

each side of the chromosome is called a chromatid they are bonded together by the centromere
The rungs are perpendicular to both sides
The Sides of this ladder equate to the Dna's Sugar-Phosphate Backbone; the Rungs of this ladder equate to the Hydrogen-bonding that takes place between base pairs.
DNA is made up of deoxyribose, phosphate, and nitrogen bases (adenine, thymine, cytosine, and guanine). The rungs of the ladder are made of two bases joined together with either two or three weak hydrogen bonds.
There are four bases in a DNA "ladder"... It is called a ladder because of the "two sides" and the bases... In DNA replication, they obviously replicate and the two sides are replicated as are the bases. (A,T,C,G)
what holds the sides of the DNA ladder together
The rungs on a ladder are held between the rails.
The two sides are formed by the four bases, Adenine, Guanine, Thymine and Cytosine. Adenine on one side of the ladder would pair with Guanine on the corresponding ladder. The same goes for Cytosine and Thymine.
The arrangement of nucleotides is based on three monosaccharides. They are 5 C sugar, 4 nitrogen acids (Adaline, Thymine, Cytosine, and Guanine), and Phosphate. They two sides of the double helix shaped DNA ladder are held together loosely by hydrogen bonds. The DNA can actually "unzip" when it need to replicate. Note that the bases attached to the sides of the ladder at the sugars and not the phosphate. lol
The DNA is in the shape of a double helix, two strands twisted together like a ladder. The sides of the ladder is made up of the sugar phosphate portions of the adjacent nucleotides bonded together. The phosphate of one nucleotide is covalently bonded to the sugar of the next nucleotide. The nitrogenous bases on either sides of the DNA stands join together to form the rung of the ladder. Each base pair is formed from complimentary nucleotides, purines with pyramidines bound together by hydrogen bonds. The base pairs in DNA are adenine with thymine and cytosine with guanine.
Yes
The backbone of the DNA molecule is made up of a sugar (deoxyribose) bonded to a phosphate group bonded to another sugar and then another phosphate and so on. These are very strong covalent bonds that are not easily broken.

Phosphate and sugar make up the sides of a DNA ladder.
The sides of the DNA ladder are composed of alternating Phosphate and deoxyribose (sugar) molecules.
In a nucleotide the 5-carbon sugar is bonded to the phosphate group, which is bonded to the nitrogenous base. In a chain of nucleotides (a strand of DNA), the nucleotides are connected by covalent bonds between the sugar of one nucleotide, and the phosphate group of the next nucleotide.
The rungs are perpendicular to both sides
