Circular DNA — is a form of DNA that is found in viruses, bacteria and archaea as well as in eukaryotic cells in the form of either mitochondrial DNA or plastid DNA. While the individual strands of a linear double helix represent two distinct and separable… … Wikipedia
circular DNA — DNA arranged as a closed circle. This brings serious topological problems for replication that are solved with DNA topoisomerase. Characteristic of prokaryotes but also found in mitochondria, chloroplasts and some viral genomes … Dictionary of molecular biology
DNA nanoball sequencing — is a high throughput sequencing technology that is used to determine the entire genomic sequence of an organism. The method uses rolling circle replication to amplify small fragments of genomic DNA into DNA nanoballs. Fluorescent probes bind to… … Wikipedia

DNA end — or sticky end refers to the properties of the end of a molecule of DNA or a recombinant DNA molecule. The concept is important in molecular biology, especially in cloning or when subcloning inserts DNA into vector DNA. All the terms can also be… … Wikipedia
DNA gyrase — DNA gyrase, often referred to simply as gyrase, is an enzyme that relieves strain while double stranded DNA is being unwound by helicase. This causes negative supercoiling of the DNA. Bacterial DNA gyrase is the target of many antibiotics,… … Wikipedia
covalently-closed circular DNA — Abbreviation: ccc DNA A DNA molecule in which the free ends have ligated to form a circle. The strands remain linked together even after denaturation. Plasmids exist in this form in their in vivo state. In its native form, ccc DNA will adopt a… … Glossary of Biotechnology
Circular bacterial chromosome — A circular bacterial chromosome, showing DNA replication proceeding bidirectionally, with two replication forks generated at the origin . Each half of the chromosome replicated by one replication fork is called a replichore . (Graphic computer… … Wikipedia
DNA virus — A DNA virus is a virus that has DNA as its genetic material and replicates using a DNA dependent DNA polymerase. The nucleic acid is usually double stranded DNA (dsDNA) but may also be single stranded DNA (ssDNA). DNA viruses belong to either… … Wikipedia
DNA supercoil — Supercoiled structure of circular DNA molecules with low writhe. Note that the helical nature of the DNA duplex is omitted for clarity … Wikipedia
DNA replication — DNA replication. The double helix is unwound and each strand acts as a template for the next strand. Bases are matched to synthesize the new partner strands. DNA replication is a biological process that occurs in all living organisms and copies… … Wikipedia
