Identify the type of bond between the two strands of DNA.
A) hydrogen bonds
B) London dispersion forces
C) dipole-dipole bonds
D) amide bonds
E) water bonds

Question

Quizplus · Accepted Answer

The type of bond between the two strands of DNA is hydrogen bonds. The nitrogenous bases in DNA (adenine, thymine, cytosine, and guanine) form complementary base pairs held together by hydrogen bonds. Adenine is always paired with thymine, and cytosine is always paired with guanine. Each base pair forms two hydrogen bonds, except for cytosine and guanine, which form three hydrogen bonds. These hydrogen bonds play a critical role in maintaining the stability and structure of the DNA double helix.
