WebMar 18, 2024 · DNA is double-sided, where the two strands are always “complementary” to each other. Adenine (A) always pairs with Thymine (T), while Guanine (G) always pairs with Cytosine (C). That means that if we know the bases on one side, then we will know the bases for the other side too. For example, if one DNA strand is TACGCTGA, then we know the ... WebMay 9, 2024 · In any DNA sample, there are four bases that pair in only one way: adenine and thymine, guanine and cytosine. They total 100 percent of the sample. Chargaff's rule states that the concentration for each base in a base pair is always equal to its mate, so the concentration of adenine equals the concentration of thymine, for example.
WebJul 7, 2024 · The chemical structures of Thymine and Cytosine are smaller, while those of Adenine and Guanine are larger. Size and structure of the specific nucleotides cause Adenine and Thymine to always pair together while Cytosine and Guanine always pair together. Therefore the two strands of DNA are considered complimentary. WebSep 14, 2024 · In both DNA and RNA, cytosine pairs with guanine ( C = G) by forming three hydrogen bonds.
