Question

how do the strategically placed covalent and hydrogen bonds present in dna facilitate the functioning of the molecule

Answer 1

Answer and explanation;

• DNA is a double stranded molecule. Covalent and hydrogen bonds pray important roles in the functioning of DNA molecules.
• Covalent bonds occur within each linear strand and strongly bond the nucleotide bases, sugars, and phosphate groups occurring both within each component and between components.
• Hydrogen bonds occur between the two strands and involve a base from one strand with a base from the second in complementary pairing.
• Hydrogen bonds helps the complementary base pairs in DNA; guanine with cytosine and adenine with thymine to connect to one another. The hydrogen bonds between these complementary pairs helps keep the two strands of DNA helix together.
