Answer :
Final answer:
RNA bases include adenine, guanine, cytosine, and uracil. Uracil pairs with adenine, guanine pairs with cytosine, cytosine pairs with guanine, and adenine pairs with thymine.
Explanation:
The nitrogenous bases in RNA are adenine (A), guanine (G), cytosine (C), and uracil (U). When matching with the DNA bases, uracil pairs with adenine, guanine pairs with cytosine, cytosine pairs with guanine, and adenine pairs with thymine.
