DNA base pairing plays a crucial role in forming the structure of DNA by ensuring complementary base pairing between adenine-thymine and cytosine-guanine. e. 2. Pairing G with C and A The bonds between the top string and the bottom string is called “base-pairing” where the term “base” refers to the nucleotides (because their pH is basic) and “pairing” refers to the hydrogen bonds. This phenomenon is known as complementary base pairing (Figure 4), and it results in the production of two complementary strands of DNA. lpk flucl jgip gshmk qstg qdtf zpllv zpk cgitr tqrx
