What is a base paring?

Base pairing refers to the specific hydrogen bonding between nucleotide bases in DNA and RNA. In DNA, adenine pairs with thymine (A-T) and cytosine pairs with guanine (C-G), while in RNA, adenine pairs with uracil (A-U) instead of thymine. This complementary pairing is crucial for the structure of nucleic acids and plays a key role in processes like DNA replication and transcription. The precise pairing ensures accurate genetic information transfer.
