Four bands appear in gel electrophoresis. Gel electrophoresis is an experimental method used to separate mixtures of DNA, RNA, or proteins by molecular size.
DNA is negatively charged, so when a current is applied to the gel, the DNA migrates towards the positively charged electrode. Fragments are ordered by size because short DNA strands migrate through the gel faster than long strands. There are some basic steps for performing gel electrophoresis outlined below. 1) pour the gel, 2) prepare the sample, 3) load the gel, 4) run the gel (expose it to an electric field), 5) stain the gel. Gel electrophoresis is a technique for separating biomolecules by size. Separation of these molecules is achieved by placing them in a small pore gel and creating an electric field across the gel

Answer:
Producers have the ability to store energy from light in organic molecules.
Explanation:
A.) Burning waste is bad because it will pollute the atmosphere. So this is not the answer.
B.) More coal based electricity will mean more smoke and ground pollution. Not the answer
--> C.) Starting recycling programs will help reuse the material rather than tossing It in a landfill. This is the correct answer.
D.) Driving cars means pollution, again, it releases carbon monoxide into the air which is bad for the ozone layer of the earth.
