Explore the structure and functions of nucleic acids including DNA and RNA with practice questions for biology exams.
RNA is usually single-stranded, while DNA contains deoxyribose and thymine instead of uracil.

Lipids are hydrophobic and do not dissolve in water. They are not polymers and play structural roles, such as forming cell membranes.
Ref: NCERT Class 11 Biology Chapter 9: Biomolecules Nucleic Acids - DNA RNA Structure and Functions
Phosphodiester bonds link nucleotides in a DNA strand by joining the phosphate group of one nucleotide to the sugar of another.
Ref: NCERT Class 11 Biology Chapter 9: Biomolecules Nucleic Acids - DNA RNA Structure and Functions
DNA contains thymine, whereas RNA contains uracil instead of thymine.
Ref: NCERT Class 11 Biology Chapter 9: Biomolecules Nucleic Acids - DNA RNA Structure and Functions
Uracil replaces thymine in RNA, whereas thymine is present in DNA.

Proteins do not store genetic information; nucleic acids (DNA and RNA) perform this function.
Ref: NCERT Class 11 Biology Chapter 9: Biomolecules Nucleic Acids - DNA RNA Structure and Functions
Nucleic acids (DNA and RNA) contain phosphodiester bonds that link nucleotides together.
Ref: NCERT Class 11 Biology Chapter 9: Biomolecules Nucleic Acids - DNA RNA Structure and Functions
Some nucleotides, like ATP and GTP, function as energy carriers in cellular metabolism.
Ref: NCERT Class 11 Biology Chapter 9: Biomolecules Nucleic Acids - DNA RNA Structure and Functions
DNA contains deoxyribose sugar, while RNA contains ribose. DNA is double-stranded, and RNA has uracil instead of thymine.
Ref: NCERT Class 11 Biology Chapter 9: Biomolecules Nucleic Acids - DNA RNA Structure and Functions
Nucleotides consist of a phosphate group, a nitrogenous base, and a sugar. They contain phosphorus, DNA contains deoxyribose, and RNA contains nitrogenous bases.
Ref: NCERT Class 11 Biology Chapter 9: Biomolecules Nucleic Acids - DNA RNA Structure and Functions
Nucleotides consist of a pentose sugar, phosphate group, and nitrogenous base and serve as the building blocks of nucleic acids.
