Troposphere-Weather such as rain, snow, and clouds occur here.

Stratosphere-Presence of the Ozone Layer

Mesosphere-Temperature decreases with altitude

Thermosphere-Temperature increases with altitude

Exosphere-Composed of helium and hydrogen

Explanation:

Troposphere is where we live in, weather such as precipitation and tornadoes reside here. The stratosphere is known for a lot of oxygen molecules, these molecules (O3) make up the ozone layer. The mesosphere contains little air molecules, and the reason why it's cold is due to the ozone layer taking the sun's rays, thus making it warmer in the stratosphere. The thermosphere is warmer due to it being the presence of the aurora borealis and australis. These are caused by ultraviolet radiation, and the average temperature there is about 500 degrees Celsius. The exosphere contains a lot of helium and hydrogen, and other heavier molecules like nitrogen, oxygen, and carbon dioxide, which reside at the exobase.

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).
