Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following would be a DNA nucleotide?
A
phosphate, deoxyribose, uracil
B
phosphate, deoxyribose, thymine
C
phosphate, ribose, uracil
D
phosphate, ribose, thymine
Explanation: 

Detailed explanation-1: -A nucleotide is the basic building block of nucleic acids (RNA and DNA). A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base. The bases used in DNA are adenine (A), cytosine (C), guanine (G) and thymine (T).

Detailed explanation-2: -DNA is made up of four building blocks called nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C).

Detailed explanation-3: -Phosphate Group in DNA Deoxyribonucleic acid (DNA) is made up of the building blocks called nucleotides. Each nucleotide comprises of three components such as a phosphate group, a nitrogenous base, and a deoxyribose.

Detailed explanation-4: -Nucleosides are the structural subunit of nucleic acids such as DNA and RNA. A nucleoside, composed of a nucleobase, is either a pyrimidine (cytosine, thymine or uracil) or a purine (adenine or guanine), a five carbon sugar which is either ribose or deoxyribose.

Detailed explanation-5: -Nucleotides that make the DNA strands contain deoxyribose sugar, phospate molecule and one nitrogenous base out of adenine, guanine, thymine and cytosine. Uracil is never a part of nucleotide of DNA.
