Base pairing

Base pairing refers to the specific way certain molecules in DNA connect to form the genetic code. DNA is made up of four types of building blocks called bases: adenine (A), thymine (T), cytosine (C), and guanine (G). These bases pair up in a precise manner: A always pairs with T, and C always pairs with G. This pairing is possible because of their shapes and chemical properties, allowing the DNA strands to form a stable double helix structure. Base pairing is essential for accurate DNA replication and transmission of genetic information.
