Nucleotide Components and DNA/RNA Structure Quiz

DNA and RNA Structure

• The nitrogenous base that forms a glycosidic bond with the 1' carbon of deoxyribose is a nucleobase (adenine, guanine, cytosine, or thymine).

RNA Composition

• Uracil is the nitrogenous base present in RNA but not in DNA.

Phosphodiester Bond

• A phosphodiester bond forms between the phosphate group and the 3' and 5' hydroxyl groups of the deoxyribose sugar.

Common Components

• The components common to both DNA and RNA nucleotides are a nitrogenous base, a five-carbon sugar (deoxyribose in DNA and ribose in RNA), and a phosphate group.

Nucleotide Sequence

• The linear sequence of nucleotides forms a polynucleotide chain or a single-stranded DNA or RNA molecule.

Test your knowledge of nucleotide components and the primary structure of DNA and RNA in this quiz. Identify the nitrogenous bases, understand the role of the 5 carbon sugar, and challenge your understanding of the linear sequence of nucleotides in DNA and RNA.
