Which of the following is a nucleotide found in DNA?

Question

a
deoxyribose + phosphate group + cytosine
b
deoxyribose + phosphate group + uracil
c
ribose + phosphate group + uracil
d
ribose + phosphate group + thymine

Answer 1

a
deoxyribose + phosphate group + cytosine

This is a nucleotide found in DNA. DNA nucleotides are composed of a deoxyribose sugar, a phosphate group, and one of four nitrogenous bases: adenine (A), cytosine (C), guanine (G), or thymine (T). Uracil (U) is found in RNA, not DNA.
