thanks.

Answer by Asst Prof
If there is a variation in width, it’s an error. Normally one pyrimidine (C, U, or T) will pair up with one purine (A or G). The purine-pyrimidine pair has a constant width. If two pyrimidines paired-up, the helix width would be smaller; if two purines paired-up, the width would be greater. However, this doesn’t normally happen, since the base-pairing is determined by hydrogen bonding characteristics.
