Answer:

DNA is often compared to a ladder becaause of its structure. The nucleotides form hydrogen bonds in a certain sequence, forming a "rung" of the ladder. The backbones of DNA are formed by alternating phosphates and  sugar residues. Each nucleotide side attatches to 1 of the 2 backbones, creating a ladder shape.

They are similar in terms of the way they are built
