Correct answer: c) Backbone—a phosphate group and a sugar

d) Rungs—bases

The DNA molecule is made up of a molecule called as a nucleotide. It consists of a Phosphate group, nitrogenous base, and a sugar group.

Each nucleotide molecule contains the four nitrogenous bases called as guanine [G], cytosine [C], adenine [A] and thymine [T], the pentose sugar and a phosphate group.

The rungs of the DNA strand are made up of nitrogenous bases and backbone of the DNA strand are composed of sugar and phosphate group.

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.
