A team grows two yeast strains (wild type and gcn2∆) in nutrient rich (R) or amino acid depleted (DR) media, extracts cellular proteins and conducts an anti-eIF2 western blot. Phosphorylated eIF2 runs higher on the gel than non-phosphorylated eIF2. What conclusions would we make about the data?

it cools slower in the earth meaning the crystals have more time to form than lava on the surface

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
