Rolling circle replication for engineering drug delivery. We report that small, single-stranded circular dna oligonucleotides 26 to 74 nucleotides (nt) in size can behave as catalytic templates for dna synthesis by several dna polymerase enzymes. the dna products are repeating end-to-end multimeric copies of the synthetic circular dnas, and range from 1 000 to >12 000 nucleotides in length., vol. 7:325-341 (volume publication date december 1973) https://doi.org/10.1146/annurev.ge.07.120173.001545.

Since rolling-circle dna replication requires a helicase-type activity, it was inferred that the primosome, or some sub-assembly or component of the primosome, was the agent responsible (28). the 4x174 ss(c) + rf dna replication system was chosen for preliminary evaluation of the ability of the pri- mosome to act as a helicase because it had simpler protein requirements than the pbr322 dna invariably linked to replication of the element in a rolling circle model (figure 1); an equivalent model to explain the behavior of phage mu was proposed independently by harshey and bukhari (1 98 1).

Helitrons on a roll eukaryotic rolling-circle transposons. Overall these results indicate that mtdna synthesis in c. elegans does not conform to any previously documented metazoan mtdna replication mechanism, but instead are strongly suggestive of rolling circle replication, as employed by bacteriophages. as several components of the metazoan mitochondrial dna replisome are likely phage-derived, these findings raise the possibility that the rolling, in molecular biology, dna replication is the biological process of producing two identical replicas of dna from one original dna molecule. this process occurs in all living organisms and is the basis for biological inheritance..

29/01/2013в в· 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 the reaction resembles rolling-circle replication of single-stranded phages and small plasmids. the displaced sense strand serves as target for an antisense reaction and vice versa, resulting in exponential growth and the autocatalytic nature of this in vitro reaction as long as the template is the limiting agent. we describe the optimization of strand displacement amplification for in vitro
