Answer:
TAC GA
Explanation:
Think of it as, TA and GC. No matter what they're both bound together. 'And yeah, the link people suck.
DNA move through an agarose gel because DNA molecules are negatively charged due to the presence of phosphate groups in their sugar-phosphate backbone which make them to move toward the positive charge in the agarose gel.
<h3>What is DNA?</h3>
Deoxyribonucleic acid or DNA is a protein molecule that us found in the nucleus of a cells which carry the genetic components or content of the cell and are transfer from parent to tye offspring.
Therefore, DNA move through an agarose gel because DNA molecules are negatively charged due to the presence of phosphate groups in their sugar-phosphate backbone which make them to move toward the positive charge in the agarose gel.

Answer:
D. all of the above
Explanation:
The water molecules have surrounded salt (NaCl) ions in the given diagram.
Salt get dissolve in water as both are polar, having positive and negative charges and both have electrical charges. Covalent bonds in water molecules are more stronger than the ionic bonds of salts, that is why salt dissolve in water.
Water molecules and salt molecules form electrostatic interaction in which the positively charges ends of water molecules are attracted to the negative chloride ions (Cl- ion) while negative ends of the water molecules are attracted to the positive sodium ion (Na+ ion).
Water molecule breaks the ionic bond between sodium and chloride ions. Water molecules form hydration shell around sodium (Na+) and calcium (Cl-) ions and allow the salt to dissolve in water and forma homogeneous solution.
Hence, the correct option is "D. All of the above".
