The chemical forces that contribute to the stability of the DNA helix are (choose the best answer): a) hydrogen bonds van der

b) Waals interactions

c) disulfide bonds

The forces that contribute to the stability of DNA helix are hydrogen bonds. That is option A.

Deoxyribonucleic acid (DNA) is a molecule found within nucleus of cells which contains genetic information that is used by the organism for development.

A molecule of DNA is made up of four nitrogenous bases which include:

The DNA helix is double which is made up of two linear strands that run opposite to each other and twist.

Hydrogen bond is defined as the intermolecular force that is capable of forming a dipole-dipole attractions.

The hydrogen bond that is formed between the nitrogenous base pair helps contributes to the stability of the DNA helix.

Therefore, the forces that contribute to the stability of DNA helix are hydrogen bonds.
