How would the shape of a DNA molecule change if adenine paired with guanine and cytosine paired with thymine?

Question

Quizplus · Accepted Answer

Adenine and guanine have different sizes, so if they paired, it would cause irregular widths along the DNA molecule's length. Similarly, cytosine and thymine also have different sizes and if they paired, there would be irregularities in DNA width. This is why adenine pairs with thymine and guanine pairs with cytosine in DNA.
