Adeninine - Thiamine and Guanine - Cytosine pairs.
The rungs of the DNA ladder would be made up of nitrogenous bases. There are four nitrogenous bases in DNA - Thymine binds to Adenine and Guanine binds to Cysteine. These bases join together to meet in the centre of the DNA helix - making the 'rungs'.

Each strand is made up of a chain of nucleotides.The two strands are held together by hydrogen bonds between adenine and thymine and between guanine and cytosine. The hydrogen bonds of DNA are analogous to the rungs of a twisted ladder. The sugar-phosphate backbones of the double helix are analogous to the sides of a twisted ladder.
helical staircase A double rung helical Staircase; in the form of a spiral ladder (10.3 rungs per turn).

a double helix- apex
The DNA backbone is also called the sugar-phosphate backbone - the deoxyribose sugars (with, among other elements, 5 carbon atoms) and phosphates (PO4--) conjoin together in a [very strong due to the electronegativity of the Oxygens] chain.Sugars and PhosphatesA sugar (deoxyribose, a sugar with, among other elements, 5 carbon atoms) and phosphates to bond them together.

because the shape is a double helix. so it looks like a zipper and connects to each other.

DNA code is simple in structure.The double helix structure of the DNA molecule is like a long ladder twisted into a spiral.
double helix
That DNA molecule is a double helix-two strands twisted around each other, like a winding staircase
The DNA molecules resembles a twisted step ladder
twisted rope ladder
AnswerThe "twisted ladder" shape of DNA is called a double helix.
the whole DNA strand looks like a twisted ladder. the molecules are on the strand.
