What is the different base that RNA has and what does it pair with?

Answer 1

RNA contains the nitrogenous base uracil (U) instead of thymine (T), which is found in DNA. In RNA, uracil pairs with adenine (A) during base pairing. Here are the specific pairings in RNA:

• Adenine (A) pairs with Uracil (U)
• Cytosine (C) pairs with Guanine (G)

This differs from DNA, where adenine pairs with thymine (T) instead of uracil.
