In this process, these enzymes change the linking number of circular DNA by 2.

The reaction generates a nicked, circular DNA which is relaxed.

The means to do this is mostly a small piece of circular DNA called plasmid or vector.

An ancient origin for the single stranded circular DNA viruses has been proposed.

The adapters are modified so that they bind to each other and form circular DNA.

The result is the completed circular DNA template.

This is significant to both proteins and genetic material, such as overwound circular DNA.

In circular DNA replication, these twists must be removed for the daughter strands to separate.

The genome is a single stranded circular DNA molecule 2600 bases in length.

The topological properties of circular DNA are complex, and only a brief introduction can be presented here.

As previously mentioned linear chromosomes face another issue that is not seen in circular DNA replication.

A circular DNA molecule with a writhe of 0 will be circular.

Catenation is the process by which two circular DNA strands are linked together like chain links.

The human mitochondrial genome is a circular DNA molecule of about 16 kilobases.

The digestion removes all but circular DNA.

The head contains the phage's double-stranded circular DNA genome.

These observations also suggest that a single endonuclease molecule is responsible for the 50% cleavage of the circular DNA.

A plasmid is a double stranded circular DNA molecule commonly used for molecular cloning.

The gaps between the flanking sequences are filled and ligated to form a circular DNA fragment.

The genetic information for tumour growth is encoded on a mobile, circular DNA fragment (plasmid).

Single stranded closed circular DNA.

First the single-stranded circular DNA is converted to a double-stranded circular intermediate.

Plasmids are small extracellular and circular DNA.

The restriction enzyme is used again to cleave the circular DNA 13 bp to the left of Ad1.

The kinetoplast(mitochondria) contains circular DNA in two forms - minicircles and maxicircles.
