Answer;
-RNA
-RNA is the molecule that demonstrates the widest range of functions due to its ability to adopt multiple conformations.
Step-by-step explanation;
-When RNA molecules folds, they often does not adopt a single, well-defined conformation. The folding energy landscape of an RNA is highly dependent on its nucleotide sequence and molecular environment.
-RNAs, particularly highly structured RNAs such as ribosomal RNA, exist in multiple conformations, many of which are likely to affect their function. Thus, when describing RNA structure, it is more accurate to discuss an ensemble of conformations instead of a single structure.
