She is using gel electrophoresis, where a DNA sample with DNA molecules of varying length are ran through an agarose gel to separate them into bands by size from longest at the top to shortest at the bottom.

Answer from: ummammaar08

Answer: Gel electrophoresis

Explanation:

Gel electrophoresis is a technique that is used to separate DNA fragments based on their size.In this technique, DNA samples are loaded into the wells at one end of a gel, and then an electric current is applied. DNA fragments being negatively charged move towards the positive electrode. Since, all DNA fragments have the same amount of charge per mass, small fragments move through the gel at a faster rate than large ones.In this way the fragments get separated by size.

Atp is is our little "pocket" of energy. of course, if you have too little, then it means you have too little energy, and you'll pass out. the way to not have enough, is to have no energy sources (glucose, fats, proteins). you can't have too many atp molecules. cycles like the krebs cycle produce it, but if you have too much of any substrate (or too little for that matter), the cycle stops and atp is no longer made (it stops until substrate levels are such that the process can go on). in any case, this is unlikely since atp is constantly hydrolyzed and remade, even while you're asleep. you won't have too much. if you have zero, you are dead or dying.

Answer from: Quest

transformative rocks are the stones that emerge from the transformation of existing rock composes in a procedure called changeability, implies changing of structures. transformative rocks are shaped from alternate shakes that are changing a result of warmth or weight connected. one of this model is the earth developments that making rocks profoundly cover or crushed which will make the stones warmed and put under awesome weight. they are not softening but rather the minerals they are containing are changed synthetically that will shape transformative rocks. now and again different rocks are shaped when the others are near some liquid magma and getting warmed.
