D) alternating purines and pyrimidines on one strand.

Question

Quizplus · Accepted Answer

A purine-rich strand base-paired to a pyrimidine-rich strand does not contribute to the conversion of B-DNA to Z-DNA. The conversion is typically facilitated by factors like the presence of 5-methylcytosine, negative supercoiling, and alternating purines and pyrimidines on one strand.
