If pyrimidines could bind to other pyrimidines,and purines could bind to other purines,what would be the impact on the DNA double helix?

Question

Quizplus · Accepted Answer

Pyrimidines binding to other pyrimidines and purines binding to other purines would result in variations in the width of the DNA double helix. This is because purines are larger than pyrimidines, and their binding to each other would result in a wider stretch of the double helix, while pyrimidines binding to each other would result in a narrower stretch. This would cause the double helix to be less regular and more variable in width.
