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.
Im not 100 percent sure, but I believe that the answer is D) because A), B), and C) are all equally necessary. Yet D) seems to have a much higher level of importance
The answer I would choose is D. Help plants by providing them with sugar
