BIOMOLECULES AND ENZYMES

Detailed explanation-1: -The DNA is hydrophilic in nature. In the DNA, the phosphorus is found in the phosphodiester bonds. This bond bears a negative charge as a surplus electron and the phosphate backbone is exposed to the surface. For this reason, they can dissolve easily with water.

Detailed explanation-2: -Each nucleotide has three hydrophilic regions: the negatively charged phosphate group, a sugar which has a number of O–H groups, and a hydrophilic edge of the base (where the N–H and N groups lie).

Detailed explanation-3: -Are nucleic acids hydrophilic or hydrophobic? Why? Nucleic acids are hydrophilic. DNA is soluble in water because the sugar and phosphate molecules that make up the DNA backbone are hydrophilic.

Detailed explanation-4: -While burial of hydrophobic residues drives protein folding, the hydrophobic effect in RNA contributes primarily to the formation of secondary structure. To form tertiary structure, RNA must overcome electrostatic repulsions from the phosphate backbone.

Detailed explanation-5: -They are hydrophilic in nature. This helps in forming bonds with water molecules. Example-DNA & RNA. Therefore, nucleic acids are soluble in water.
