D-loop

This triple-stranded structure is called a displacement loop or D-loop.

This changes the D-loop to a cross-shaped structure known as a Holliday junction.

Replication begins with replication of the heavy strand starting at the D-loop (also known as the control region).

Strand invasion forms a joint DNA molecule called a D-loop.

The function of the D-loop is not yet clear, but recent research suggests that it participates in the organization of the mitochondrial nucleoid.

In humans, the protein RAD51 is central to the homologous search and formation of the D-loop.

If the D-loop is cut, another swapping of strands forms a cross-shaped structure called a Holliday junction.

This back-cast is often referred to as the "D-loop", from the curving shape of the line between the anchor and the tip of the rod.

Partially overlapping fragments are then used for synthesis of homologous regions through a moving D-loop that can continue extension until they find complementary partner strands.

Mutations in the D-loop can effectively track recent and rapid evolutionary changes such as within species and among very closely related species.

A displacement loop (D-loop) is formed during strand invasion between the invading 3' overhang strand and the homologous chromosome.

Nowadays, it is regarded as one of the most distinct species in the mallard group, based on behavioural and mtDNA D-loop sequence comparisons.

Three proposed mechanisms have strand invasion as an initial step, but they differ in how they model the migration of the D-loop and later phases of recombination.

The invading 3' overhang causes one of the strands of the recipient DNA duplex to be displaced, to form a D-loop.

Another definition for branch migration is the extension of a D-loop when a single stranded DNA strand invades a "recipient" duplex during recombination or repair.

The filament searches for the homologous chromosome, strand invasion occurs where the new chromosome forms a D-loop over the bottom sister chromatid, then the ends are annealed.

A diagram in the paper introducing the term illustrated the D-loop with a shape resembling a capital "D", where the displaced strand formed the loop of the "D".

Resolution of the D-loop is thought to occur by replication primed by the 3' end generated at Chi (in the D-loop).

Once strand invasion has occurred, a displacement loop, or D-loop, is formed, at which point either SDSA or a double Holliday junction occurs.

There is a structure in subdomain 2 that is called the "D-loop" because it binds with DNase I, it is located between the His40 and Gly48 residues.

The D-loop occurs in the main non-coding area of the mitochondrial DNA molecule, a segment called the control region or D-loop region.

In Gawesworth's hands, the gentle sweep of the rod is effortless as it forms the "D-loop" that is central to the cast; with a forward stroke, his line hisses through the guides.

Apennine birds are not consistently recognizable by external morphology, and are only weakly differentiated with regards to mtDNA D-loop and hypervariable control region sequences and microsatellite genotyping.

In 2006, the Bornean slow loris was elevated to the species level (as Nycticebus menagensis) based on molecular analysis of DNA sequences of the D-loop and the cytochrome b gene.

The control region and mtDNA D-loop are sometimes used synonymously in the literature; specifically the control region includes the D-loop along with adjacent transcription promoter regions.
