WebG-quadruplex structures can be computationally predicted from DNA or RNA sequence motifs, but their actual structures can be quite varied within and between the motifs, which can number over 100,000 per genome. Their activities in basic genetic processes are an active area of research in telomere, gene regulation, and functional genomics research. WebDNA and RNA Structures Nucleic acids have a primary, secondary, and tertiary structure analogous to the classification of protein structure. The sequence of bases in the nucleic acid chain gives the primary structure of DNA or RNA. The sequence of bases is read in a 5′ → 3′ direction, so that you would read the structure in the next figure as ACGT.
