Practice question
Question
Which secondary structure is formed by guanine-rich sequences?
Explanation
G-quadruplex accurately describes the structural composition or molecular organization asked about in this question. In Nucleic Acid, knowledge of molecular structure is directly linked to understanding biological function. The specific arrangement of chemical components in G-quadruplex determines its physical properties, biological activity, and interactions with other molecules. The other options (Z-DNA, Triple-stranded DNA, and A-DNA) describe different structural arrangements, incorrect stoichiometry, or compositions of different biological molecules.
