Question

base pairing always occurs between two pyramidines, but never between a purine and a pyrimidine

Answer 1

Hello,

I'm assuming you are trying to determine if the statement you typed is true or false. The answer is false.

Purines = adenine and guanine

Pyrimidines = cytosine and thymine

Adenine (A) pairs with Thymine (T) , while Guanine (G) pairs with Cytosine (C).

Therefore, base pairing does occur between purines and pyrimidines.

Hope this helps!
