Question

Hydrophobic bases are located on the _______ of the double helix, the hydrophilic phosphate and deoxyribose residues are located on the _________.

Answer 1

Hydrophobic bases are located on the inside of the double helix, while the hydrophilic phosphate and deoxyribose residues are located on the outside of the double helix.

Step-by-step explanation:

The hydrophobic bases are located on the inside of the double helix, while the hydrophilic phosphate and deoxyribose residues are located on the outside of the double helix.

This arrangement allows the hydrophobic bases, which are nonpolar, to be shielded from the surrounding aqueous environment, while the hydrophilic phosphate and deoxyribose residues, which are polar, interact with water molecules.

In the DNA double helix, the hydrophobic bases, such as adenine, cytosine, guanine, and thymine, pair with each other through hydrogen bonding, forming base pairs that stabilize the helix.
