Adenine is one of the four nucleobases found in DNA and RNA. In DNA, adenine always pairs with thymine through two hydrogen bonds, forming the traditional Watson-Crick base pair. This pairing is essential for the stability and replication of the DNA molecule.
The Watson-Crick base pairing rules, proposed by James Watson and Francis Crick in 1953, dictate that adenine (A) always pairs with thymine (T), while guanine (G) always pairs with cytosine (C). This complementary base pairing is crucial for the accurate transmission of genetic information during DNA replication and transcription.
Understanding the base pairing rules is fundamental in molecular biology and genetics. It allows scientists to predict the sequence of one strand of DNA based on the sequence of the complementary strand. This knowledge is essential in various fields, including genetic engineering, forensics, and evolutionary biology.
