In the DNA double helix, the two strands are held together by which type of bonds?
- A.Hydrogen bonds
- B.Covalent bonds
- C.Ionic bonds
- D.Peptide bonds
Show correct answer & step-by-step solution
Correct answer: A — Hydrogen bonds
Solution
- The DNA double helix consists of two antiparallel strands.
- Complementary base pairing occurs between adenine and thymine, and guanine and cytosine.
- These base pairs are stabilized by hydrogen bonds.
- Hence the answer is (A).
