Upon insulin binding, the extracellular domain is converted into a T-shaped conformation that brings the transmembrane domains together.

Temperate Grassland  Temperatures in the winter often fall below –10ºC, while summers may be very hot, approaching 30ºC, and summer droughts are not uncommon.  Annual rainfall is generally between 25 and 100 cm, too low to support a forest but higher than that in deserts.  Prairie soils are among the richest in the world, having a nutrient content much greater than that of a typical forest soil.

Steps in determining gene order in a three-point cross 

Identify the non-recombinant progeny

Identify the double-crossover progeny

Compare the phenotypes of double-crossover progeny with the phenotypes of non- recombinant progeny

The characteristic that differs between the double crossover and the non-recombinant progeny is encoded by the middle gene
