The process of gel electrophoresis taps on the property of net charges of molecules to ensure that they travel up the gel. Additionally, the buffer acts as the mobile phase for the molecules and also give molecules net charge as they travel through the gel. It is until the molecules reaches an isoelectric point,where the molecule has zero net charge, that they stops moving through the gel. This is how bands are formed.
<h2>Which of the following subatomic particles do NOT have a charge?
</h2><h2>a) protons
</h2><h2>b) electrons
</h2><h2>c) neutrons

If Anna’s doctor recommends getting 60% of her calories from carbohydrates, it means that (2000*.60) or 1200 calories should come from carbohydrates.
<span>If one gram of carbohydrate provides 4 calories of energy, then 1200 calories is equal to (1200/4) or 300 grams of carbohydrates Anna should consume each day.</span>
