Does DNA ever take different shapes other than the double helix?

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. WebDNA topoisomerases are important targets of approved and experimental anti-cancer agents. Topoisomerase II is an essential enzyme that is required for virtually every process that requires the movement of DNA within the nucleus or the opening of the double helix. There are two subclasses of type II topoisomerases, type IIA and IIB.
