Rolling circle replikation
Rolling circle replication (RCR) is a process of unidirectional nucleic acid replication that can rapidly synthesize multiple copies of circular molecules of DNA or RNA, such as plasmids, the genomes of bacteriophages, and the circular RNA genome of viroids. Some eukaryotic viruses also replicate their DNA or RNA … See more Rolling circle DNA replication is initiated by an initiator protein encoded by the plasmid or bacteriophage DNA, which nicks one strand of the double-stranded, circular DNA molecule at a site called the double-strand origin, or … See more RCA can amplify a single molecular binding event over a thousandfold, making it particularly useful for detecting targets with ultra-low abundance. RCA reactions can be performed in not only free solution environments, but also on a solid surface like glass, micro- or … See more • DNA replication systems used with small circular DNA molecules Genomes 2, T.

WebAn endonuclease enzyme produces a nick in the + strand, exposing a free 3′ end and a free 5′ end (Fig. 14.12). DNA synthesis begins by addition of deoxyribonucleotides by the enzyme DNA polymerase to the free 3′ end of the + strand using the strand as template. The minus strand revolves while serving as template hence the name rolling circle.
