Answer:
Deoxyribose sugar and phosphate are found in all the DNA nucleotides, while the bases, that is, guanine, cytosine, thymine, and adenine are found only in particular DNA nucleotides.
DNA comprises two strands of building blocks known as DNA nucleotides. Each nucleotide of DNA comprises a deoxyribose sugar, a phosphate group, and a nitrogen-containing base. The two components, that is, the phosphate group and deoxyribose sugar are common to all the DNA nucleotides, while the nitrogen-containing base group will differ.
There are four kinds of nitrogen-containing bases, that is, guanine, adenine, cytosine, and thymine. These bases associate in particular manners with adenine producing hydrogen bonds with thymine, and guanine pairing with cytosine. These associations of complementary bases connect the two strands of DNA that then twist to produce the characteristic helical composition of DNA.
