Chemical genetics is the investigation of the function of proteins and signal transduction pathways in cells by the screening of chemical libraries of small molecules. [1] Chemical genetics is analogous to classical genetic screen where random mutations are introduced in organisms, the phenotype of these mutants is observed, and finally the ...
A coastal path (or a littoral path) is a trail along a sea shore or a lake shore for pedestrians, and sometimes for cyclists or equestrians. Some coastal paths were originally created for use by customs or coastguard officials looking out for smugglers landing illicit goods. In modern times some routes have been developed for tourists, with ...
The coast path then reaches St Alban's Head, just to the south of the village of Worth Matravers. Between St Alban's Head and the resort of Swanage is Durlston Country Park nature reserve; from Worth Matravers to Swanage the coast path follows the route of the Priest's Way . [ 71 ]
Also called functionalism. The Darwinian view that many or most physiological and behavioral traits of organisms are adaptations that have evolved for specific functions or for specific reasons (as opposed to being byproducts of the evolution of other traits, consequences of biological constraints, or the result of random variation). adaptive radiation The simultaneous or near-simultaneous ...
The following outline is provided as an overview of and topical guide to genetics: . Genetics – science of genes, heredity, and variation in living organisms. [1] [2] Genetics deals with the molecular structure and function of genes, and gene behavior in context of a cell or organism (e.g. dominance and epigenetics), patterns of inheritance from parent to offspring, and gene distribution ...
Molecular genetics is a branch of biology that addresses how differences in the structures or expression of DNA molecules manifests as variation among organisms. Molecular genetics often applies an "investigative approach" to determine the structure and/or function of genes in an organism's genome using genetic screens.
Coastal geography is the study of the constantly changing region between the ocean and the land, incorporating both the physical geography (i.e. coastal geomorphology, climatology and oceanography) and the human geography (sociology and history) of the coast.
In mammals, its path is unusually long. As a part of the vagus nerve, it comes from the brain, passes through the neck down to heart, rounds the dorsal aorta and returns up to the larynx, again through the neck. (Fig. 2f) This path is suboptimal even for humans, but for giraffes it becomes even more suboptimal. Due to the lengths of their necks ...
