What is the composition of the nucleotides in the chromosome structure?

Question

Quizplus · Accepted Answer

A nucleotide consists of a pentose sugar (ribose or deoxyribose), a phosphate group, and a nitrogenous base. The chromosome structure is composed of DNA which is made up of nucleotides. Therefore, the composition of nucleotides in the chromosome structure includes ribose or deoxyribose, phosphate, and a nitrogenous base. Choice A is incorrect because DNA is not a composition of nucleotides, but rather nucleotides are the building blocks of DNA. Choice C is incorrect because pyrimidines are a type of nitrogenous base and are not considered a separate entity from adenine, thymine, guanine, and cytosine. Lastly, choice D is incorrect because uracil is not present in the chromosome structure as it is only present in RNA instead of DNA.
