Adenine and Thymine
Guanine and Cytosine held together by hydrogen bonds: 2 for A-T and 3 for G-C

Chemical bonds hold together the atoms within a molecule. The most common types of chemical bonds are covalent bonds and ionic bonds. Covalent bonds involve the sharing of electrons between atoms, while ionic bonds involve the transfer of electrons from one atom to another.
Hydrogen bonds are the strongest of the intermolecular forces that hold molecules together. They are important because the presence or absence of hydrogen bonds determines many physical and chemical characteristics of the compound in question. For example, a molecule with significant hydrogen bonding will have a much higher boiling point than one with no hydrogen bonding.
Cytosine (C) and guanine (G) nucleotides are held together by three hydrogen bonds in the DNA double helix. This bonding contributes to the stability of the DNA structure, allowing for the specific pairing between these complementary bases. The three hydrogen bonds between C and G are stronger than the two hydrogen bonds formed between adenine (A) and thymine (T).
Carbohydrates is a very broard class of sugar molecules and monomers can join in many ways. 1,4- beta glycosidic bonds 1,4- alpha glycosidic bonds 1,6 glycosidic bonds 1 and 6 are refering to the carbon molecules and Beta and alpha refer to the orientation of the sugars with respect to each other. But for a simple answer they connect to each other by glycosidic bonds.
DNA bases are held together by hydrogen bonds. Adenine pairs with thymine through two hydrogen bonds, while guanine pairs with cytosine through three hydrogen bonds. These interactions contribute to the stability of the DNA double helix structure.

There are many types of bonds and forces that bind molecules together. The two most basic types of bonds are ionic and covalent.
Hydrogen.
In his rookie season of 1986, Barry Bonds stole 36 bases.

The bases in a DNA double helical chain are paired A-T and C-G. The A and T bases are bound by 3 hydrogen bonds per pair, and the C and G bases are bound by three hydrogen bonds per pair.
Chemical bonds hold together the atoms within a molecule. The most common types of chemical bonds are covalent bonds and ionic bonds. Covalent bonds involve the sharing of electrons between atoms, while ionic bonds involve the transfer of electrons from one atom to another.
In 2001, Barry Bonds stole 13 bases.
In water and many other compounds hydrogen and oxygen are held by covalent bonds.Between water molecules and between other polar molecules hydrogen of one molecule and oxygen of a different molecule are held by hydrogen bonds.
The energy stored in the bonds that hold together atoms and molecules of substances is called chemical potential energy. This energy is released when bonds are broken and new bonds are formed during chemical reactions.
Two hydrogen bonds connect adenine and thymine.
