In molecular biology, a displacement loop or D-loop is a DNA structure where the two strands of a double-stranded DNA molecule are separated for a stretch and held apart by a third strand of DNA. An R-loop is similar to a D-loop, but in that case the third strand is RNA rather than DNA.
Multiple displacement amplification (MDA) is a DNA amplification technique. This method can rapidly amplify minute amounts of DNA samples to a reasonable quantity for genomic analysis. The reaction starts by annealing random hexamer primers to the template: DNA synthesis is carried out by a high fidelity enzyme, preferentially Φ29 DNA polymerase.
Displacement (linguistics), the ability of humans (and possibly some animals) to communicate ideas that are remote in time and/or space; Forced displacement, by persecution or violence; Displacement (psychology), a sub-conscious defense mechanism; Displacement (parapsychology), a statistical or qualitative correspondence between targets and ...
Displacement activities occur when an animal or human experiences high motivation for two or more conflicting behaviours: the resulting displacement activity is usually unrelated to the competing motivations. Birds, for example, may peck at grass when uncertain whether to attack or flee from an opponent; similarly, a human may scratch their ...
Brown and Wilson used the term character displacement to refer to instances of both reproductive character displacement, or reinforcement of reproductive barriers, and ecological character displacement driven by competition. [1] As the term character displacement is commonly used, it generally refers to morphological differences due to competition.
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
In fluid mechanics, displacement occurs when an object is largely immersed in a fluid, pushing it out of the way and taking its place. The volume of the fluid displaced can then be measured, and from this, the volume of the immersed object can be deduced: the volume of the immersed object will be exactly equal to the volume of the displaced fluid.
In cellular biology, traction force microscopy (TFM) is an experimental method for determining the tractions on the surface of a cell by obtaining measurements of the surrounding displacement field within an in vitro extracellular matrix (ECM).
