Detailed explanation-1: -Deoxyribo-nucleic Acid (DNA) consists of simple sugar, phosphate and four nitrogen bases.
Detailed explanation-2: -A molecule consisting of a nitrogen-containing base (adenine, guanine, thymine, or cytosine in DNA; adenine, guanine, uracil, or cytosine in RNA), a phosphate group, and a sugar (deoxyribose in DNA; ribose in RNA).
Detailed explanation-3: -A nucleotide is the building block of nucleic acids (a type of macromolecule). It is made up of three main parts: phosphate group(s), pentose sugar, and a nitrogenous base (adenine, thymine, guanine, cytosine, or uracil).
Detailed explanation-4: -Deoxyribonucleic acid (DNA) is made up of sugar, a nitrogenous base and a phosphate group (Figure 1.2). The combination of these molecules makes the building blocks for the DNA synthesis.
Detailed explanation-5: -The basic unit of a nucleic acid is a nucleotide. It is formed by a nitrogenous base, a sugar and a phosphate group. The nitrogenous bases that bind to the sugar are of two types; purines consisting of adenine and guanine and pyrimidines consisting of cytosine, thymine in DNA and uracil in RNA.
