* Adenine (A) with Cytosine (C)
* Guanine (G) with Thymine (T)
Why?
DNA and RNA use specific base pairing rules:
* Adenine (A) pairs with Thymine (T) in DNA and Uracil (U) in RNA.
* Guanine (G) pairs with Cytosine (C) in both DNA and RNA.
These pairings are based on the chemical structures of the bases, allowing for the formation of hydrogen bonds between them. This is crucial for maintaining the stability and function of DNA and RNA.
