Base pairing refers to the specific hydrogen bonding between complementary nucleotide bases in DNA and RNA. In DNA, adenine (A) pairs with thymine (T), and guanine (G) pairs with cytosine (C). In RNA, adenine (A) pairs with uracil (U) instead of thymine. This base pairing is essential for the accurate replication and transcription of genetic information, as well as for the stability and structure of the DNA double helix. **

Without meeting these requirements, villagers will not pair up and breed. **
