<u>Answer</u>:

Run gel electrophoresis should be the next step.

<u>Explanation</u>:

In this phase, fragments of the DNA  are separated OR segregated based on their sizes. DNA samples are placed in one end of  gel and electricity is passed to drag them through the gel. The fragments of DNA are made up of  negative charge, that’s why they move across the positive electrode. If this process will continue for long time , DNA will shift off the end of gel. To move through the gel it requires high voltage. If the voltage becomes very high it will lead to melting of gel or smearing of the DNA bands.

The ATP molecule can be considered a form of chemical energy because?
Wittaler [7]

Answer: The correct answer is A) It stores the energy from the glucose in the bonds between the phosphate groups.

ATP ( adenosine triphosphate) is considered as a form of chemical energy as the energy is stored in the high energy phosphoanhydride bonds, which are present between phosphate.

Whenever a body requires energy, glucose is metabolized and produces ATP. The energy from glucose molecule is stored in the ATP.

When ATP is hydrolyzed, it is converted into ADP ( adenosine diphosphate) and inorganic phosphate and the large amount of energy is released.

Margarita [4]
Glucose and oxygen are required for cellular respiration. As the law of conversation states, in a biochemical reaction, mass is conserved. For every glucose molecule, 6 oxygen molecules are used up and the end products, other than the energy dissipated by the reaction, are 6 water molecules and 6 carbon dioxide molecules. The mass of hydrogen in the glucose is therefore conserved in the water molecules products
