During the isolation of Bacterial DNA, the mixture (Cell debris, genetic material, and proteins in buffers) is transfered to a centrifuge tube and treated with an equal volume of chloroform:isoamyl alcohol (24:1 v/v) solution. This is then manually shaked for 15 minutes and centrifuged for 10 minutes at 3000rpm. Following centrifugation, 3 layers are observed in the tube; name the layers accordingly and state what is contained within them:

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
