As a summary, a typical DNA rolling circle replication has five steps: [2] Circular dsDNA will be "nicked". The 3' end is elongated using "unnicked" DNA as leading strand (template); 5' end is displaced. Displaced DNA is a lagging strand and is made double stranded via a series of Okazaki fragments. Replication of both "unnicked" and displaced ...
DNA Nanoball Sequencing involves isolating DNA that is to be sequenced, shearing it into small 100 – 350 base pair (bp) fragments, ligating adapter sequences to the fragments, and circularizing the fragments. The circular fragments are copied by rolling circle replication resulting in many single-stranded copies of each fragment. The DNA ...
In the single stranded DNA viruses—a group that includes the circoviruses, the geminiviruses, the parvoviruses and others—and also the many phages and plasmids that use the rolling circle replication (RCR) mechanism, the RCR endonuclease creates a nick in the genome strand (single stranded viruses) or one of the DNA strands (plasmids).
The key parts are highly similar for all embodiments of SBS and include (1) amplification of DNA to enhance the subsequent signal and to attach the DNA to be sequenced to a solid support, (2) generation of single stranded DNA on the solid support, (3) incorporation of nucleotides using an engineered polymerase and (4) detection of the ...

A restriction map is a map of known restriction sites within a sequence of DNA.Restriction mapping requires the use of restriction enzymes.In molecular biology, restriction maps are used as a reference to engineer plasmids or other relatively short pieces of DNA, and sometimes for longer genomic DNA.
Prokaryotic DNA Replication is the process by which a prokaryote duplicates its DNA into another copy that is passed on to daughter cells. [1] Although it is often studied in the model organism E. coli, other bacteria show many similarities. [2] Replication is bi-directional and originates at a single origin of replication (OriC). [3]
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 ...
