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 via the rolling circle mechanism.
Monodnaviria is a realm of viruses that includes all single-stranded DNA viruses that encode an endonuclease of the HUH superfamily that initiates rolling circle replication (RCR) of the circular viral genome. Viruses descended from such viruses are also included in the realm, including certain linear single-stranded DNA (ssDNA) viruses and ...
Orthopoxvirus particles. A DNA virus is a virus that has a genome made of deoxyribonucleic acid (DNA) that is replicated by a DNA polymerase.They can be divided between those that have two strands of DNA in their genome, called double-stranded DNA (dsDNA) viruses, and those that have one strand of DNA in their genome, called single-stranded DNA (ssDNA) viruses. dsDNA viruses primarily belong ...
This is accomplished by rolling circle replication with the Phi 29 DNA polymerase which binds and replicates the DNA template. The newly synthesized strand is released from the circular template, resulting in a long single-stranded DNA comprising several head-to-tail copies of the circular template. [ 10 ]
The method uses rolling circle replication to amplify small fragments of genomic DNA into DNA nanoballs. Unchained sequencing by ligation is then used to determine the nucleotide sequence. [ 128 ] This method of DNA sequencing allows large numbers of DNA nanoballs to be sequenced per run and at low reagent costs compared to other high ...
(The Center Square) – Mass transit legislation is once again on the table for members of the Illinois General Assembly. State Rep. Eva-Dina Delgado, D-Chicago, introduced House Bill 3778. The ...
WASHINGTON (Reuters) -U.S. law enforcement and intelligence agencies are concerned about copycat vehicle-ramming attacks following the New Year's Day attack in New Orleans by a U.S. Army veteran ...
The observed DNA replication intermediates included circular and branched circular concatemeric structures that likely arose by rolling circle replication. When assembling concatemers from synthetic oligonucleotides, increasing salt concentration to 200 mM was found to be a major optimizing factor due to its ability to enhance ionic strength ...
