Question: Bonds by which base pairs are linked in dna?

If you are interested in learning about the bonds by which base pairs are linked in DNA, you might find this blog post helpful. It explains the basic structure and function of DNA, and how the bases form hydrogen bonds with each other.

DNA, or deoxyribonucleic acid, is the molecule that stores genetic information in living organisms. It is composed of two strands of nucleotides, which are the building blocks of DNA. Each nucleotide has three parts: a sugar, a phosphate, and a nitrogenous base. The sugar and phosphate form the backbone of the DNA strand, while the bases stick out from the backbone.

The bases are of four types: adenine (A), thymine (T), cytosine (C), and guanine (G). These bases can form **hydrogen bonds** with each other, which are weak attractions between hydrogen atoms and other atoms. Hydrogen bonds are important for holding the two strands of DNA together and maintaining the shape of the DNA double helix.

However, not all bases can bond with each other. There are specific rules of **base pairing** that determine which bases can form hydrogen bonds. These rules are:

- A pairs with T, forming two hydrogen bonds

- C pairs with G, forming three hydrogen bonds

These rules are also called **Watson-Crick base pairing**, named after the two scientists who discovered the structure of DNA in 1953. Base pairing ensures that the distance between the two strands of DNA is constant, and that the DNA helix is stable and regular.

Base pairing also has another important function: it allows DNA to be copied accurately during cell division. Since each base on one strand has a complementary base on the other strand, the sequence of bases on one strand can be used as a template to make a new strand with the same sequence. This process is called **DNA replication**, and it ensures that genetic information is passed on from one generation to the next.
