Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following would be a nucleotide found in DNA
A
Ribose + phosphate + uracil
B
Deoxyribose + phosphate + uracil
C
Deoxyribose + phosphate + adenine
D
Ribose + phosphate + adenine
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). The nucleotides attach to each other (A with T, and G with C) to form chemical bonds called base pairs, which connect the two DNA strands.

Detailed explanation-3: -These chemical bonds act like rungs in a ladder and help hold the two strands of DNA together. There are four nucleotides, or bases, in DNA: adenine (A), cytosine (C), guanine (G), and thymine (T).

Detailed explanation-4: -Nucleic acids are biopolymers comprised of nucleotide monomers that are composed of three moieties, a five-carbon sugar, a phosphate group, and a nitrogenous base. DNA contains deoxyribose as the sugar component and RNA contains the sugar ribose.

Detailed explanation-5: -Adenine is found in DNA and it’s a nitrogenous base. It’s a nucleotide building block for DNA and it has two rings fused together. Adenine always pairs with thymine. The chemical formula for Adenine is C5H5N5.
