Verified step by step guidance
1
Understand the basic structure of nucleic acids: DNA and RNA are composed of nucleotides, each containing a sugar, a phosphate group, and a nitrogenous base.
Identify the nitrogenous bases in DNA: DNA contains four bases - Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).
Identify the nitrogenous bases in RNA: RNA contains four bases - Adenine (A), Uracil (U), Cytosine (C), and Guanine (G).
Compare the bases found in both DNA and RNA: Look for bases that appear in both lists. Adenine (A) and Guanine (G) are present in both DNA and RNA.
Conclude which bases are common to both DNA and RNA: Adenine and Guanine are the bases that can be found in both DNA and RNA.
