The rungs of the DNA ladder are made up of pairs of nitrogenous bases. DNA, or deoxyribonucleic acid, has a structure that looks like a twisted ladder, which is called a double helix. The sides of the ladder are made of sugar and phosphate molecules, while the rungs are formed by the nitrogenous bases.
There are four different nitrogenous bases in DNA:
1. Adenine (A)
2. Thymine (T)
3. Cytosine (C)
4. Guanine (G)
The bases pair up in a specific way: Adenine always pairs with Thymine (A-T), and Cytosine always pairs with Guanine (C-G). These pairs are held together by hydrogen bonds, and that’s what makes the rungs of the DNA ladder!
