Question

Similarity in DNA and RNA is ______.

Options

• both are polymer chains of nucleotides.

• both have similar sugars.

• both have similar pyrimidines.

• both are in single stranded polynucleotide chains.

Answer 1

Similarity in DNA and RNA is both are polymer chains of nucleotides.

Explanation:

Both DNA and RNA are nucleic acids that function as polymers, meaning they are long chains made up of repeating structural units called nucleotides. Each nucleotide in both molecules consists of a phosphate group, a five-carbon sugar, and a nitrogenous base. While they differ in their specific sugars (deoxyribose vs ribose) and one of their bases (thymine vs uracil), their fundamental “blueprints” as polynucleotide chains are identical.
