Answer:
Sharing electrons occurs when atoms have a covalent bond. Covalent bonds occur between non-metals and there are two types of covalent bonds: Polar and Nonpolar Covalent bonds. Polar covalent bonds are when there is an unequal sharing of electrons which causes the atom that occupies the electron(s) more to have a slightly negative charge while the atom that occupies the electron(s) less has a slightly positive charge. Nonpolar covalent bonds basically have equal sharing of the electron(s).
Atoms bond because they need to become stable like the noble gases.

Answer:
The correct answer is c.With an RNA virus, radioactive RNA would have been in the final pellet.
Explanation:
Hershey and Chase infected<em> E.coil</em> with bacteriophage which was having DNA as its genetic material. The bacteriophage was labeled with radioactive sulfur and radioactive phosphorus and it was radioactive phosphorus that was found in the bacterial cells or pellet.
As because DNA contains phosphorus, not protein therefore they it was proved that DNA is the genetic material. Similarly, RNA is also a nucleic acid which is genetic material for many viruses and contains phosphorus.
So if Hershey and chase might have chosen an RNA virus then radioactive RNA would have been present in the pellet. So the correct answer is c.
The answer to your question is two DNA molecules. 2 both copies consist of one new chain and one old chain nucleotides. half of the chain is part of the original DNA molecule the other brand new molecule
