In DNA, adenine (A) can bond with thymine (T) through two hydrogen bonds, while guanine (G) can bond with cytosine (C) through three hydrogen bonds. This complementary base pairing is essential for the stability of the DNA double helix structure.
A Lewis base is a molecule or ion that donates an electron pair to another atom to form a covalent bond. It is a species that can provide a pair of electrons to form a new bond. Lewis bases are electron-pair donors.
Another name for the electrovalent bond is an ionic bond.
Hydroxide is a Lewis base because it is a species that can donate a pair of electrons to form a coordinate covalent bond with another species that accepts those electrons, such as a proton in an acid-base reaction. The hydroxide ion (OH-) has a lone pair of electrons that it can donate to form such a bond.
Another name for a dative covalent bond is 'coordinate covalent bond'.
A substance is a Brønsted-Lowry base if it can accept a proton from another substance. This process involves the base acting as a proton acceptor in a chemical reaction. A Brønsted-Lowry base usually contains a lone pair of electrons that can bond to a proton.
no.because there is not enough space to bind two purine bases.

hydrogen bond
The bond between a pyrimidine nitrogen base and a pentose sugar in DNA or RNA is a glycosidic bond. This bond forms between the carbon atoms of the nitrogenous base and the carbon atoms of the pentose sugar.
A substance is a Brønsted-Lowry base if it can accept a proton from another substance. This process involves the base acting as a proton acceptor in a chemical reaction. A Brønsted-Lowry base usually contains a lone pair of electrons that can bond to a proton.
Yes, a base can accept a proton from a hydroxide ion, forming a new chemical bond. When this happens, the base becomes protonated.
the bond is called a hydrogen bond:)
Yes, in DNA, a single ring base (such as thymine or cytosine) pairs with another single ring base (adenine or guanine). This forms the complementary base pairs that allow DNA strands to bond together through hydrogen bonding.
A Bronsted-Lowry base is a species that can accept a proton (H+ ion) from another substance. It must have a lone pair of electrons to bond with the proton and form a new bond. This lone pair of electrons allows the base to act as a proton acceptor and participate in acid-base reactions.
