Question

The sugar molecule in a nucleotide is​

Answer 1

Answer-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.

Answer 2

Ribose Sugar (in RNA) and Deoxyribose Sugar (in DNA)

Explanation:

• Ribose Sugar: The sugar molecule with molecular formula (C₅H₁₀O₅) is present in the monomer i.e. nucleotide molecule of a nucleic acid named as ribonucleic acid (RNA) which is known as the genetic/ hereditary material of some organisms like viruses (Bacteriophage and TMV).
• Deoxyribose Sugar: The sugar molecule with molecular formula (C₅H₁₀O₄) is present in the monomer i.e. nucleotide molecule of a nucleic acid named as deoxyribonucleic acid (DNA) which is known as the genetic/ hereditary material of organisms like all eukaryotic organisms such as plants and animals.
