The hydrophilic nature of DNA is due to the presence of – (1) thymine base (2) Biotic resources (3) phosphate group (4) deoxyribose sugar

1 Answer

Answer :

(2) Biotic resources Explanation: The phosphate groups on DNA are ionic and charged. Each phosphategroup on the DNA back-bone is one unit of negative charge (-1). Charged molecules attract water and are hydrophilic. DNA has two hydrophilic polar external backbones made of sugars and phosphate groups joined by ester bonds.
