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.

Haplogroup R is a widely distributed human mitochondrial DNA (mtDNA) haplogroup. Haplogroup R is associated with the peopling of Eurasia after about 70,000 years ago, and is distributed in modern populations throughout the world outside of sub-Saharan Africa. [4] Haplogroup R is a descendant of the macro-haplogroup N.
R-L21 or R1b1a2a1a2c, also known as R-M529 or R-S145, is a Human Y-chromosome DNA haplogroup. It is often linked to the Insular Celts . [ 1 ] One subclade, R-DF13 comprises over 99% of bearers.
(Austin, "Genotype," n.d.) Genetic Engineering is a field of work and study within microbial genetics. [1] The usage of recombinant DNA technology is a process of this work. [1] The process involves creating recombinant DNA molecules through manipulating a DNA sequence. [1] That DNA created is then in contact with a host organism.
For example, the standard protocols for DNA fingerprinting involve PCR analysis of panels of more than a dozen VNTRs. RFLP is still used in marker-assisted selection. Terminal restriction fragment length polymorphism (TRFLP or sometimes T-RFLP) is a technique initially developed for characterizing bacterial communities in mixed-species samples.

Oligonucleotides are short DNA or RNA molecules, oligomers, that have a wide range of applications in genetic testing, research, and forensics.Commonly made in the laboratory by solid-phase chemical synthesis, [1] these small fragments of nucleic acids can be manufactured as single-stranded molecules with any user-specified sequence, and so are vital for artificial gene synthesis, polymerase ...
