Hi. A normal ladder does not twist, DNA does twist.

A normal ladder is made up of two straight lines which shorter straight lines connecting them. The two longer lines remain parallel within one plane. The shorter cross lines (the steps) are also parallel to one another within the same plane.
DNA is a twisted ladder for lack of a better description. It's shape is technically a double-helix. Imagine taking a ladder and tiwsting its ends in opposite directions thereby causing it to "wind up" quite a bit.

yeah. DNA is a "double-helix" like the helix when you ride a roller-coaster. also the rungs of a normal ladder are one piece of the same material while the DNA "rungs" are made up of 4 nucleotide bases: adenine, thymine, guanine, cytocine. 2 pair together to make a rung and the pairs are always a and t,c and g.

the width of a normal ladder is the same all along, it's the same in DNA.
