Practice question
Question
The B-DNA helix contains how many base pairs per turn?
Explanation
10.5 accurately describes the structural composition or molecular organization asked about in this question. In DNA, knowledge of molecular structure is directly linked to understanding biological function. The specific arrangement of chemical components in 10.5 determines its physical properties, biological activity, and interactions with other molecules. The other options (9, 11, and 12) describe different structural arrangements, incorrect stoichiometry, or compositions of different biological molecules.
