Detailed explanation-1: -The rungs of the DNA ladder made of four types of nitrogenous bases . These are adenine (A), guanine (G), cytosine (C), and thymine (T). These nitrogen bases pair as A-T and C-G with the help of two and three hydrogen bonds respectively.
Detailed explanation-2: -Other combinations of the atoms form the four bases: thymine (T), adenine (A), cytosine (C), and guanine (G). These bases are the rungs of the DNA ladder. (It takes two bases to form a rung–one for each side of the ladder.)
Detailed explanation-3: -Attached to each sugar is one of four bases: adenine (A), cytosine (C), guanine (G) [GWA-NeeN] or thymine (T). The two strands are held together by hydrogen bonds between pairs of bases: adenine pairs with thymine, and cytosine pairs with guanine.
