Webepisomal circular double-stranded (ds) AAV-HBV DNA monomers and multimers (formed by recombination, [31, 32]) as well as, hypothetically, the HBV cccDNA formed by re … cccDNA (covalently closed circular DNA) is a special DNA structure that arises during the propagation of some viruses in the cell nucleus and may remain permanently there. It is a double-stranded DNA that originates in a linear form that is ligated by means of DNA ligase to a covalently closed ring. In most cases, … See more Closed covalent circular DNA (cccDNA) is a unique DNA structure that forms in response to infection of a cell. Genomic DNA enters the cell nucleus, and partially double-stranded DNA is then converted into cccDNA. See more CccDNA is able to form a stable minichromosome in the nucleus of cells that are infected with a particular virus associated with cccDNA. As part of the nucleus, cccDNA is … See more CccDNA is formed from rcDNA (relaxed circular DNA) through the removal of a viral polymerase on the 5’ end of the negative strand of … See more CccDNA is associated with the hepatitis B virus (HBV), where the virus constructs its plasmid through covalently linking its bonds. The histone-containing region of the nucleus within … See more
