Nucleic acid structure is made up of monomer unit called nucleotide. Each nucleotide is composed of a five-carbon sugar, a phosphate group and five types of nitrogenous bases.
The nitrogenous bases are categorized in two forms the purines (adenine and guanine ) and the pyrimidines (cytosine, thymine and uracil). The "purines" contain double rings in their structure due to which they appear larger in size than pyrimidines which are made up of single rings.
Thus, Option-B is the correct answer.

Answer:
uhh either natural and reproductive pretty sure it's reproductive
After cell division, each daughter cell has : B. a higher surface area/volume ratio than the parent cell
With this occurrence, the daughter cell will have an advantage after the cell division
hope this helps
