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: -Thus, the six components of DNA are deoxyribose sugar, phosphate, and four nitrogenous bases, i.e. adenine, guanine, thymine, and cytosine.
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: -The basic elements that compose DNA are five atoms: carbon, nitrogen, oxygen, phosphorous, and hydrogen. A nucleoside is the combination of these atoms into two structures, a five-carbon sugar molecule called deoxyribose, which is responsible for the name of DNA, and a phosphate group.
Detailed explanation-5: -Nucleic acids are giant biomolecules made of monomers called nucleotides. Nucleotides have three components: pentose sugar (5-carbon sugar), phosphate group, and nitrogenous base.
