A) nucleoside
B) nucleotide
C) nucleic acid
D) pyrimidine base
Correct Answer: B
Solution :
A nucleotide is formed by the union of a phosphate group with a nucleoside. A nucleoside, intact, contains a sugar molecule along with an organic nitrogen base. Thus, a nucleotide contains an organic nitrogen base along with a sugar molecule and a phosphate group, i.e., Nucleoside = Sugar molecule + organic nitrogenous base Nucleotide = Nucleoside + phosphate group.
