Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following is a nucleotide found in DNA?
A
ribose + phosphate group + uracil
B
deoxyribose +phosphate group+cytosine
C
ribose + phosphate group + thymine
D
deoxyribose + phosphate group + uracil
Explanation: 

Detailed explanation-1: -DNA is made up of four building blocks called nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C).

Detailed explanation-2: -Deoxyribose is one of the three components of nucleotides, the building blocks of DNA. Each nucleotide consists of a phosphate group, a nitrogenous base-adenine (A), thymine (T), cytosine (C), or guanine (G)-and deoxyribose.

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: -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-5: -Deoxyribose+phosphate group+cytosine is a nucleotide found in DNA.
