DN, dN, or dn may refer to:
DNA sequencing is the process of determining the precise order of nucleotides within a DNA molecule. It includes any method or technology that is used to determine the order of the four bases—adenine, guanine, cytosine, and thymine—in a strand of DNA.
In molecular biology, DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule.
In molecular biology, DNA polymerases are enzymes that synthesize DNA molecules from deoxyribonucleotides, the building blocks of DNA.
The Dnieper Flotilla (Днепровская военная флотилия) is the name given to the various naval flotillas on the Dnieper River.
Dnipropetrovsk (Ukrainian: Дніпропетро́вськ [ˌdnʲiprɔpɛˈtrɔwsʲk], officially Dnipro, Дніпро) or Dnepropetrovsk (Russian: Днепропетро́вск [dnʲɪprəpʲɪˈtrofsk]), is Ukraine's fourth largest city, with about one million inhabitants.
Deoxyribonucleic acid (/diˈɒksiˌraɪboʊnjʊˌkliːɪk, -ˌkleɪɪk/; DNA) is a molecule that carries the genetic instructions used in the growth, development, functioning and reproduction of all known living organisms and many viruses.
A DNA microarray (also commonly known as DNA chip or biochip) is a collection of microscopic DNA spots attached to a solid surface.
DNA methylation is a process by which methyl groups are added to the DNA molecule. Methylation can change the activity of a DNA segment without changing the sequence.
DNA repair is a collection of processes by which a cell identifies and corrects damage to the DNA molecules that encode its genome.
