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.
Detailed explanation-3: -The two strands are held together by hydrogen bonds between pairs of bases: adenine pairs with thymine, and cytosine pairs with guanine.
Detailed explanation-4: -A rung is one of the horizontal steps of a ladder. You should never stand on the very top rung of a ladder-it can be dangerous!
Detailed explanation-5: -The rungs of the ladder are formed by complementary pairs of nitrogen bases — A always paired with T and G always paired with C.
