Non-B DNA is DNA in any conformation other than the canonical (B-DNA) conformation, the most common form of DNA found in nature at neutral pH and physiological...

Non-coding DNA (ncDNA) sequences are components of an organism's DNA that do not encode protein sequences. Some non-coding DNA is transcribed into functional...

common B-DNA form. Z-DNA is thought to be one of three biologically active double-helical structures along with A-DNA and B-DNA. Left-handed DNA was first...

the Structure of DNA. The DNA double helix biopolymer of nucleic acid is held together by nucleotides which base pair together. In B-DNA, the most common...

into DNA strands during processes such as transcription and DNA replication. DNA exists in many possible conformations that include A-DNA, B-DNA, and...

Non-B DB is a database integrating annotations and analysis of non-B DNA-forming sequence motifs. The database provides alternative DNA structure predictions...

DnaB helicase is an enzyme in bacteria which opens the replication fork during DNA replication. Although the mechanism by which DnaB both couples ATP hydrolysis...

Junk DNA (non-functional DNA) is a DNA sequence that has no known biological function. Most organisms have some junk DNA in their genomes—mostly pseudogenes...

each other and form a triple helix. In triple-stranded DNA, the third strand binds to a B-form DNA (via Watson–Crick base-pairing) double helix by forming...

Mitochondrial DNA (mtDNA and mDNA) is the DNA located in the mitochondria organelles in a eukaryotic cell that converts chemical energy from food into...

Cruciform DNA is a form of non-B DNA, or an alternative DNA structure. The formation of cruciform DNA requires the presence of palindromes called inverted...

DNA repair is a collection of processes by which a cell identifies and corrects damage to the DNA molecules that encode its genome. A weakened capacity...

Sequence-specific DNA-binding proteins generally interact with the major groove of B-DNA, because it exposes more functional groups that identify a base pair. DNA-binding...

The DNA damage theory of aging proposes that aging is a consequence of unrepaired accumulation of naturally occurring DNA damage. Damage in this context...

Y-chromosome DNA haplogroup is a haplogroup defined by specific mutations in the non-recombining portions of DNA on the male-specific Y chromosome (Y-DNA). Individuals...

Her work was central to the understanding of the molecular structures of DNA (deoxyribonucleic acid), RNA (ribonucleic acid), viruses, coal, and graphite...

In molecular biology, DNA replication is the biological process by which a cell makes exact copies of its DNA. This process occurs in all living organisms...

Ancient DNA (aDNA) is DNA isolated from ancient sources (typically specimens, but also environmental DNA). Due to degradation processes (including cross-linking...

Haplogroup B (M60) is a human Y-chromosome DNA haplogroup common to paternal lineages in Africa. It is a primary branch of the haplogroup BT. B (M60) is...

Hepatitis B virus (HBV) is a partially double-stranded DNA virus, a species of the genus Orthohepadnavirus and a member of the Hepadnaviridae family of...
