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:
DNA is the recipe for how to build your body's proteins and mRNA is an index card it copies the DNA but doesn't have to stay in the nucleus. (1st option)
Explanation:
DNA carries genetic instructions for developing, growing and reproducing all known organisms and many viruses. mRNA, on the other hand, collects the DNA's instruction to the cells' protein-making part.
