DNA

Which sugar conformation is preferred in Z-DNA?

C2'-endo is the scientifically accurate answer to this question. Within the study of Nucleic Acid, this concept is well-established through extensive research and is documented in standard scientific literature. The specific properties, mechanisms, or characteristics of C2'-endo directly address what is being asked. Among the other options, C3'-endo, C2'-exo, and C3'-exo do not correctly answer this question because they either refer to different concepts, describe properties of other molecules or processes, or represent common misconceptions about this topic.

DNA

Which of the following DNA structures contains alternating purine and pyrimidine sequences?

Z-DNA 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 Z-DNA determines its physical properties, biological activity, and interactions with other molecules. The other options (A-DNA, B-DNA, and Triple-stranded DNA) describe different structural arrangements, incorrect stoichiometry, or compositions of different biological molecules.
