DNA Structure and Function Review

Nitrogenous bases are located on both strands of the DNA double helix. What is the significance of the nitrogenous bases?

• The number of adenines and cytosines determines the type of RNA that will be produced.

• The order of nitrogenous bases determines the order of amino acids in the proteins synthesized.

• The amount of thymine and guanine in the DNA molecules determines the length of the genes.

• The type of hydrogen bonding between the nitrogenous bases determines which amino acid will be added to the peptide chain.
