Respuesta :
The nucleotide bases are the nitrogenous rings that form the backbone of the nucleic acid. Robins and sparrows have the same bases with different arrangements. Thus, option C is correct.
What are nucleotide bases?
The nucleotide bases or the nucleobases are the fundamental units that together with the sugar molecule and phosphate make the structure of the DNA or RNA.
There is a total of five nucleotide bases divided into purines and pyrimidines based on their ring structures. The purine consists of adenine and guanine, pyrimidine of cytosine, uracil, and thymine.
The bases are universal in organism containing the DNA or RNA but only differs in their arrangements that result in the development of the various traits and characteristics of the organism.
Therefore, in option C. the bases are arranged differently in species.
