Nucleic acids like DNA and RNA consist of polymers of nucleotides
BIOXI09: BIOMOLECULES

Identify the building block for DNA and RNA
1 Nitrogen base
2 Nucleoside
3 Nucleotide
4 Sugar
Explanation:
For nucleic acids, the building block is a nucleotide. A nucleotide has three chemically distinct compounds, i.e. one is a heterocyclic nitrogenous base compound, second is a pentose monosaccharide and the third is a phosphoric acid or a phosphate group.

Which of the following pairs of nitrogenous bases of nucleic acids is wrongly matched with category mentioned against it?
1 Adenine, Thymine – Purines
2 Thymine, Uracil – Pyrimidines
3 Uracil, Cytosine –Pyrimidine
4 Guanine, Adenine – Purines
Explanation:
The two-carbon nitrogen ring bases (adenine and guanine) are purines, while the one-carbon nitrogen ring bases (uracil, thymine and cytosine) are pyrimidines.
