Your friend is studying mouse fur color and has isolated the GPCR responsible for determining its color, as well as the extracellular signal that activates the receptor. She finds that, on addition of the signal to pigment cells (cells that produce the pigment determining fur color), cAMP levels rise in […]

Gene of unknown function in the mouse genome was investigated with reverse genetic approach Knock out mouse was created was missing particular gene When phenotype of investigated mouse was compared the only difference from the wild-type was mouse kicking other mouse And I know the protein encoded was named KST […]

A locus in Australian Bearded Dragons is involved in the production of pigment. When heterozygous parents mate, 75% of the progeny are colored and the rest are albino. Another phenotype concerns the specific colors that are expressed such that when two green bearded dragons mate, 2/3 of the progeny are […]

The maintenance of homeostasis is of major importance to all organ systems in the body and the overall survival of the individual. Explain how homeostasis is the maintenance of a dynamic range of environmental qualities rather than holding the internal environment at a set point. What would be wrong with […]
