Schematic representation of factors promoting R-loop formation and stabilization. An R-loop is a three-stranded nucleic acid structure, composed of a DNA:RNA hybrid and the associated non-template single-stranded DNA. R-loops may be formed in a variety of circumstances and may be tolerated or cleared by cellular components.

If a vital gene is knocked out it can prove lethal to the organism. In order to study the function of these genes, site specific recombinases (SSR) were used. The two most common types are the Cre-LoxP and Flp-FRT systems. Cre recombinase is an enzyme that removes DNA by homologous recombination between binding sequences known as Lox-P sites ...
Used to assemble recombinant DNA molecules and to direct their replication within host organisms. [12] Molecular biology: Northern blot: Used to study gene expression by detection of RNA (or isolated mRNA) in a sample.

This list of DNA nanotechnology research groups gives a partial overview of academic research organisations in the field of DNA nanotechnology, sorted geographically.Any sufficiently notable research group (which in general can be considered as any group having published in well regarded, high impact factor journals) should be listed here, along with a brief description of their research.
The researchers used data from 17 actual cases to test their model. In each case, the target’s DNA—that of the suspect or the victim—produced anywhere from 200 to 5,000 matches.
Haplogroup R, or R-M207, is a Y-chromosome DNA haplogroup. It is both numerous and widespread among modern populations. It is both numerous and widespread among modern populations. Some descendant subclades have been found since pre-history in Europe , Central Asia and South Asia .
