WebThe Utilities page enables depiction of secondary structures with ideal helical geometry for stacked base pairs, as for this complex of three RNA strands with A-form helices (left) or three DNA strands with B-form helices (right). Sequences can be exported to the Analysis page for further examination in the context of a dilute solution. WebThe replication complex is the group of proteins that help synthesize the new DNA strands. A replication unit is any chunk of DNA that is capable of being replicated — e.g. a plasmid with an origin of replication (ORI) is a replication unit. Alternatively, this can also mean a region of DNA that is replicated together.

"WebRNA chains fold back on themselves to form hairpin loops or stem-loops, so that these sequences can form helices. Many of the helical stems in RNA hairpins are interrupted by internal loops, which is to say regions where sequences are juxtaposed that can-not form GCs, AUs, or wobble GUs, which most regard as “honorary” Watson-Crick base pairs.
