Base pair
A base pair is a fundamental unit of DNA structure, consisting of two Nucleotides that are bonded together through Hydrogen bonds. The base pairing rules state that Adenine (A) always pairs with Thymine (T), and Guanine (G) always pairs with Cytosine (C). This complementary base pairing is crucial for the replication and transcription of Genetic material. The discovery of the base pairing rules is attributed to James Watson and Francis Crick, who described the structure of DNA in 1953. Understanding base pairs is essential for Molecular biology and has led to significant advances in Genetic engineering and Gene editing.
