What physical feature of dna is affected by the pairing of purines with pyrimidines?

Biology
1 answer:
denis-greek [22]3 years ago
4 0

Answer:

Its width.

Explanation:

The size of pyrimidines and purine is different because each group has a different structure (1 or two rings). Therefore, the width of DNA is "constant".

If we would pair two pyrimidines or two purines, the width of DNA would be different in both cases.

Hope this will help :)
