|
|
Phosphorus
|
|
|
Oxygen
|
|
|
Nitrogen
|
|

Explanation:
Detailed explanation-1: -Nucleic acids contain the same elements as proteins: carbon, hydrogen, oxygen, nitrogen; plus phosphorous (C, H, O, N, and P).
Detailed explanation-2: -The base pairs are stabilized by hydrogen bonds; adenine and thymine form two hydrogen bonds between them, whereas cytosine and guanine form three hydrogen bonds between them. Figure 22.2. 7: Hydrogen bonds form between complementary nitrogenous bases on the interior of DNA.
Detailed explanation-3: -Both interactions are of equal importance in nucleic acids. The two strands of a DNA molecule are held together by the hydrogen bonding between the related bases.
