Answer:
B) The mass of the reactants equals the mass of the products,
Explanation:
Given that the reaction is balanced, the mass of the reactants must equal to the mass of the products.
We know this by virtue of the law of conservation of mass.
The law of conservation of mass states that "in a chemical reaction, matter is neither created nor destroyed but atoms are rearranged".
Therefore, if the reaction is chemically balanced, the mass of reactants must be the same as the mass of the products in the reaction.
The second choice is the right one.

In the year 1952, two scientists, Hershey and Chase conducted a series of experiments that helped to establish the fact that DNA is a genetic material. The DNA is located inside the nucleus of living cells in form of chromosomes and its the determinant of traits that are found in living organisms. During protein synthesis, the information in the DNA molecule is encoded into an RNA molecule and this is used in the production of protein, thus, DNA actually directs all the happen in the living cells.
